Used GMC cars for sale near Oceanside, 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.

My husband and I had a good experience in this dealer. Great service, friendly and professional.

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.

The response time was really fast, I had received an email back within an hour. I was actually surprised how quick they had contacted me about my inquiry and I would recommend them to a friend

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

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.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Jason Jaffe , Luis Lopez and Chris from the finance department all gave me 5 star ⭐️ ⭐️⭐️⭐️⭐️ service . Leasing my new 4 runner and trading in my vehicle went very smooth from start to finish . The smoothest car buying experience ever . Thank you so much to each of these employees for your excellent 5 star service . I highly recommend these employees and Mossy Toyota for a great car buying experience .

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

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!

Sisco was awesome. Had us in the perfect car and did the paperwork without a fuss or dickering. Very straight forward. Simply the best car buying experience ever!

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.

I had the pleasure working with Jesus. He is very knowledgeable and patient with us. After a few test we were able to decide on the car we wanted. We were able to finalize the deal. Process was smooth. I would like to thank Nissan Temecula, especially Jesus in making it happen.

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

Thank you DCH for making it so. Nick, the affable and knowledgeable sales person, guided me through the low pressure decision. As I waited in the sales room during the process, I could hear the other deals being discussed in a personable manner from a team confident in their product and caring for their customer. This is the experience you want for your friends and family. I recommend Nick and DCH Honda to anyone looking for a great car and a friendly helpful team.

This dealership provides the best service in the valley. Samantha is very helpful every time I need something done on my BMW.

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.

The best and easiest purchase experience I've ever had. Kevin Sale was friendly, helpful, with excellent communication throughout my whole purchase. Jeff and the rest of the Encinitas staff were A+ as well.

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.

My husband Paul and I recently purchased a '06 Saturn ION from CarMax in Kearney Mesa. We were greeted with friendly and professional service. The purchase went smoothly and we are happy with our Saturn Ion.

I just purchased it new. Love it. the interior, the way it rides. Its a great bang for the dollar. A must own. I wish the MPG was a little better

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.

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.

I came into test drive a pre-owned car and Greyson was awesome. Friendly and knowledgeable!

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?

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.

The GMC Terrain is a very dependable auto that I have had no issues. The model is the AT4, which has the headsup display. Interior is nice with leather and all the electronics options.

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.

I had the car I wanted transferred in and from start to end they kept me informed. The waiting period was a bit of a bummer, but knowing that my car was arriving made it worth the wait. Ryan was super he completed the transaction and put us in good hands. We had a minor defect with the windows but Ryan made sure it was taken care of . Overall we were quite pleased. We're definitely getting a second car with them . Lidia

To be honest, this SUV impressed me with the great performance even with the small 1.5 liter engine, and huge space inside, it rides like a bigger vehicle, very responsive on the highway and very quiet cabin. My wife really liked 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!

Found Mercedes Benz through Cars.com and worked with Nick. Had an amazing experience purchasing my used E-class. Would recommend this dealership to friends and family everyone was extremely knowledgeable and helpful.

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.

Good service, professional staff. People very courteous and friendly. Dealer ship is very clean and well-organized.

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
