Used GMC cars for sale near Oceanside, CA under $40,000

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

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

Barely made into Oceanside from AZ with engine problems, spoke with Kal Chatham in Service and he did an excellent job of getting my truck in, diagnosed and informed of the problem. Fixed in one day, picked up the morning afterward and made the return to AZ with family aboard. Thanks Kal

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.

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

We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

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.

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 .

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 bought a Dodge Charger R/T here. I just want to say that I had excellent treatment. Professional, courteous, and welcoming!

Just trade in my 2015 GMC Denali with 140000 miles on it and still holding strong at trade in best SUV I ever had upgraded to the new 2021 Denali and boy do I love this SUV from comfort to outside design just an amazing new well designed SUV.

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

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!

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

They were very responsive and answered all my questions promptly and honestly. I was very impressed

Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

Very good service facility. Knowledgeable of my needs and work and Kept me informed well. Work was done in the time they said. Will use them again.

We love our GMC Terrain !! We recently purchased from former Mike Duman in Suffolk, VA which is now Priority Mitsubishi our salesman Mr.Knight is highly recommended He’s a man of God, great respectable person, and very professional!! Whenever you are in the area and you’re looking to purchase a vehicle contact Mr.Mervis Knight !!

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.

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.

My experience with Ken in the service department is truly a 10/10 every time. He?s so helpful, informative, and reliable. Not only is he a great help, he also is so welcoming and kind when we visit!

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.

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.

Bought it from my sister. Best vehicle I've owned. Very comfortable and has plenty of power. Love it. It's like anything else you own, regular care & maintenance goes a long way.

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 fell in love with my GMC Terrain when I test drove it and have not lost that loving feeling! I have received tons of compliments on it.

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.

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.

25 000 miles on it so far No issues at all Power is fine Bluetooth is terrible Memory seats need work Lumbar is a bad design

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!
