Used GMC cars for sale near Camp Pendleton South, CA under $40,000

What an amazing experience! I had the pleasure to have John Khalil as my sales agent, who happens to not only be a welcoming and zealous sales agent at CarMax of Oceanside, CA, but also a very talented painting artist!! He had great compassion for my autistic son and made sure he was always comfortable during the efficient waiting process by offering him a cute CarMax car toy, a CarMax coloring book and crayons. He went above and beyond when complex situations came about during the bank’s verification process. The determination he had to push my situation through with his persistent diligence as I watched him communicate with high professionalism and positivity as a team with his colleagues/finance management team was remarkable!!!! Thank you, CarMax of Oceanside, CA!! You all are an amazing TEAM!! I’m so happy with my car!!!

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

I've been taking my car for service here since 2021. Excellent service dept! Emerson is the best service guy! Recently he fixed a problem I had since I bought the car and told me about it when I picked up my car. A most excellent surprise. Hands down top notch service. Highly recommend.

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

Very communicative and help helpful through the buying process. Offer the best prices definitely recommend.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

Brian was knowledge and made time from his other responsibilities to work with us. The car we called about was ready and waiting for us when we arrived. This was our first (and likely not last) CarMax experience.

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

I really liked this dealership. Finding the the car I want and everything was smooth. Everybody is very helpful and honest. Overall I would come back

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Highly recommended. A+++ on all accounts. I came early in the morning, I was the 1st customer and within 2 minutes I was approached by a very kind and professional sales representative David. I was checking out if they have specific cars and features that I wanted like leather seats, Hybrid, etc,. He was very knowledgeable, friendly, professional and really listened to my needs. Non aggressive, good energy, easy going. If you want a good sales rep ask for David. Customer Service was excellent. By the way, I am female who drove many different cars so I was aware what I like, like and pros and cons of different features which often correlates directly with price itself. I had a budget that I was willing to spend and maximum number of miles on a car. David completely understood my needs. No pressure whatsoever. Sales rep with common sense! I really liked that everyone I encountered that day had amazing listening skills. This was the 1st and only location I visited and I ended up buying a car that same day. I did not feel the need to go anywhere else. This seemed like a good team to do business with and so I purchased used Toyota Prius v. I did research prior to visiting this location and cars offered through Carfax, another fantastic website. This Escondido location had big selection of cars. I picked 1 out of at least 4 Toyota Prius vehicles on the lot, I got exactly the car I wanted and fantastic experience. Financing option was easy easy and short. Less than 5 minutes. They need your stated income, DL and then after submission, different banks offer different interest rates based on your credit rating. I lowered both my interest and monthly payment by offering larger down payment. However, that's up to you. 20% down definitely gives you better options. At the end I received copy of all documents included Carfax print out. All nicely put together in the folder by a manager. I did drive for about 30 min 2 cars prior to purchase. Highway and streets. I liked optional insurance products such as GAP and LoJack Theft Deterrent. Although I was asked if I want it, it's optional, I was willing to pay extra $795 for each, however now I have vehicle that can be tracked and recovered if stolen by police. I also checked You Tube videos on this, and I love it. The manager Diego gave me Free Oil Check for the future, number for insurance that ended up giving me cheap rate yet fantastic policy the following day. Vehicle I bought was all nice and clean, everything ready and prepared to go! Great people, great experience, highly recommend.

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

We buy 2 vehicles and got the best deal, and planning to buy 2 more cars and hope to get the better deal then ever.

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

Dylan was amazing! The experience was easy and relaxing. I felt Dylan listened to my needs and never felt any pressure. He was professional and kind.

Such great service that I drive only to this location. Alex is always so nice & helpful.

I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.

Perfect . If you want to get good emotions then you need this GMC Yukon Denali XL . L M k if you have any questions please

No complaints, all praise and compliments! I admire carmax business model, and them having a no negotiation rule is a beautiful thing. Ray was my consultant and we sold our 2012 forte to buy an suv. Message me if you have any questions and I will answer them.

One of the most attractive looking t cars GMC has ever designed. Looks just like a Lexus. Extremely roomy. Love every aspect of my Terrain.

This was my first time visiting your store and Mesa was very informative and helpful.

Missing a few things that could really make it better. Homelink for garage door isn’t offered? Doesn’t come with a receiver type hitch however what does comes with it is almost the same amount of steel. The phone charger doesn’t work quite right and they know it.

Had a great experience with their service department. They did great work on my GMC Yukon. Keep me informed on all the worked they performed. Definitely a great dealer to work with.

GMC Diesel Canyon AT4. I've had this truck for a year-11,000 miles. I love it. The Denali and Elevation trim looked like junk. The AT4 can't compete with the Tacoma off road but, It holds it's own off road. The Diesel pulls like a beast and the exhuast brake, on all the moutain passes I drive, is worth it's wieght in Gold. I trailer the max. capacity regularly and it's smooth sailing. I traded in my 2500HD Silverado with the vortec 6.0 for this big, little truck. Best decision I've made in a while. I had this truck on order for 8 months and Gm never accepted the order. I finally found exactly what I ordered, just off the truck that morning that I called. 1300 miles away, I jumped on a plane to go get it. Crying shame GMC discontinued the diesel. The extra $ per gallon right now is easily washed by the increase in mileage, 32+ higway, 19 trallering almost 8000 #'s. I wouldn't want the truck without it. Wouldn't want the Elevation or Denali. Diesel AT4 is the truck. I'll keep it the rest of my life barring accident. I'm sure I can get 40 years out of this truck doing 10-12k a year. The regeneration of the exhaust has never come up but, I only do a little round town driving. Most of my miles are highway and hauling a load. I've heard horror stories about regen. from city folk, commuters... You get what you aim for. If you've given it a lot of thought and the diesel AT4 seems right for you, you won't be disappointed. Good luck finding one. GM - You've a winner here. don't let it get away. Ps. Cars.com doesn't have a choice of how I use this truck for WORK. And wouldn't let me submit this review without selecting one of thier 3 inadequate choices. So, I selected having fun cause I believe everything should be but, this is my WORK TRUCK!

Excellent overall experience. Sales representative was not the most knowledgeable, but was very attentive. The facility was clean and sales did not apply pressure. Representative made several follow-up calls which were appropriate and helpful to my search.

I love my 2022 GMC Canyon Elevation. The V6 engine is great. Good gas mileage, even for the way I drive it! Great comfort and very stylish. All around, just a great truck.

Autonation Mazda is a great place to buy one of the best cars. Mitchel and Fred are the best. They are super friendly and helpful. Go and see them today. Great sales men. ⭐⭐⭐⭐⭐. Thank you very much.

I just purchased a 2018 Acadia and I’ve been having oil pan issues. I took it back to open road in New Jersey where I purchased it for a high price repair and am still having issues

Buying a car was so easy and transparent with Encinitas Ford. Loved working with Larry (sales) and Dan (finance). Such a better experience than I had with another dealership.

So far I have been enjoying my 2025 GMC Canyon Denali. It has a great ride and is very comfortable. The Canyon drives very nicely and has plenty of power for my usage (I don't tow anything). It tracks well and has a very smooth ride that rivals previous BMWs (328 and X5's). I have had zero issues but the vehicle is only 1.5 months old (approx 1,700 miles on it). THe only downside (which many people agree on) is that it is seriously lacking storage space. Center console storage is about 1/2 what it was in my 2020 Jeep Wrangler and under seat storage (rear seats) is almost useless ..very little space. That being said, I'd still recommend the GMC Canyon and hope it continues to impress me.

No pressure to purchase. The vehicle appears to be in great condition. Sales person very knowledgeable

I purchased my 2016 GMC Terrain SLT in 2018 as a gently used vehicle with only 21,000 miles on it. I never had issues with it. I kept it regularly serviced and had to replace tires. At now over 93,000 it has been a comfortable and very reliable car. The only feature I wished it had was rear air conditioning. Living here in the SE it gets hot and it takes a “minute” to get the back of the vehicle cooled down. However, I rarely have back seat passengers, and thankfully, the really hot weather lasts only a few months! I have been very pleased with this car and would recommend it to others. I traded it in a week ago for a larger car only because I need the room for a grandchild, and my elderly parents.

Came in to take a look at some cars. Everyone was very helpful and they had a lot more cars than any dealer I’ve been to in a while. Ask for Jake, he’s the man!

I have owned my Acadia just under one year. It is quiet, stylish, has an easy and very effective infotainment system, owns five star safety and shows every indication of being as reliable as the Yukon I owned for 20 years. This Suv will go to 60 mph in about 6.0 seconds flat. It has 20 inch wheels and tires and will turn better and stop faster than most every Suv. I have front and rear heated seats, cooled seats, a sunroof, memory settings and this is only an SLT. My gas mileage routinely exceeds EPA (with AWD). Driving from Milwaukee to Chicago, I averaged 29.8 MPG at 75 mph. EPA is 26 MPG at 65 mph. I truly LOVE that Car and Driver rates this SUV near the bottom. Better for me. I have the Home Run. The OWNERS of the GMC Acadia rate this SUV higher than Highlander Palisade, Explorer, Telluride and all the rest. Count me among them. FYI, not a GM employee, just a happy customer.

Had an enjoyable experience at Kearny Mesa Chevrolet. They have a wide selection of vehicles on their lot. All of the vehicles were show room ready. Our sales guy Uriel helped us pick the right Silverado for us. He was very helpful thru the entire process. The GM Michael was very personable and checked that we were well taken care of. We highly recommend Kearny Mesa Chevrolet!

2019 Canyon Denali. All sorts of bells and whistles, several that I don't really need. Biggest complaint: no memory seats and no Homelink garage opener. Ridiculous. What accountant made that decision?
