Used GMC cars for sale near Montclair, CA under $20,000

LSM Cars by far has been the best car buying experience I have ever had. They were very honest, sincere and made the whole buying process easy from start to finish. My sales rep Teo was very knowledgeable and patient while Erika the finance manager was looking to get me approved with one of their banks. I ended up trading in my 2010 Honda civic for a 2018 Mercedes-Benz GLE. I love my new car thanks again LSM Cars team. I will definitely be back for my next and will make sure my friends and family come to see you guys as well.

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 bought a Chevy Silverado from LSM Cars and had a great experience overall. The staff was friendly and very knowledgeable about the inventory. Erika and Mike made sure everything was handled properly and efficiently. The pricing was fair and the process was transparent. This dealership truly cares about their customers. I’ll definitely be back in the future.

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

i greatly appreciate diamond auto for helping me buy my car ,they were very very helpful with the process ,i will defiantly return in the future

I bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

I came looking for a couple of trucks for my business and i found exactly what i was looking for i bought three units for my business i would have almost double the amount if i would have bought new...they allowed me to take the vehicles out to the franchise dealer and some things needed to be fixed so they took care of those little details got me commercial financing and i was pretty much on my way I recommend this dealer no doubt they have a huge inventory you just have to do your own due diligence...

It's exactly what I was looking for; used but not too used, low miles, good looking but not too many bells and whistles, and didn't need any work.

I bought a 2017 Kia Optima, my credit was a bit challenging was ready to give up until I came across metro auto. Called in I got an appointment the same day . About 3 hours I came out with a new car . Thank you metro auto team !

This is a really nice vehicle for being used. It exceeds our expectations for comfort and performance. We enjoy driving it both in town and out in the country.

Excellent service here. Totally professional and very kind. I have nothing but positive things to say about them. Thank you very much David and P!

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 recently was in need to buy a new car for my son. We found A&A Auto on our computer, liked the cars they had posted and decided to go in. We were greeted by a very knowledgeable salesman, Larry. Despite my son being very picky, Larry showed great patience with my son. We decided on a 2015 Nissan. This car was clean on the inside and out and had new tires. The finance manager, Burt explained the whole lending process and was very upfront with answering all my questions. Overall, this was an excellent experience and my son was extremely happy with his car and his monthly payment. Thanks A&A. Your team is the best!!

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 !

Dealer ship sounds good, have not personally gone to find out for my self yet. But when I’m ready I will go take a look

This Yukon is very roomy, comfortable, has tv for my kids. New tires, great condition Best vehicle I have ever owned. I highly recommend it.

Buen Servicio nos explicate en nuestro idioma exelente travajadoer los recommends y regresaremos muy pronto

READ PLEASE I love my Terrain. DO NOT get the 1.5 L. My engine has barely made it over 100,000 I have had $6k of repairs in less than a year. Things keep going wrong now. I had NO issues before. Catalytic converter went out 75-85k miles. My turbo was just replaced. Just beware of this type of engine… every mechanic that worked on it shared this is not uncommon for this type. I would definitely get another terrain but not the 1.5!

Honestly the best experience you'll have buying a car. My salesman Antoine Fiveash (Tony) was awesome. Non stressful environment and friendly faces. Tony talked to me like a real person and not just another sale. I walked out happy with my new car I got for a killer deal!! I'll be back for my next car

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

Benjamin was really kind, explained all the options and wasn’t harassing at all. Car in good condition so far !!

This vehicle is exactly what I was looking for! It has all the options I was looking for, even the color. Lots of leg and overall room in all 3 rows. Good on fuel with the DOD option. Very high safety and crash ratings! GM products have always been dependable for me!

Es exelete lugar para comprar carros buen servicio y buenos precios sin duda el mejor lo recomiemdo siempre a todos deberian de ingresar es buen lugar

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.

Bryan made everything easy and the process was fast. The car shopping experience wasn’t as dreadful as I thought it would be.

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 !!

very satisfied, great service and value. friendly and helpful team. very easy to get appointment and fast service. I've been going to this dealership for years.

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.

These guys are the best in the business, honest and transparent will definitely be coming back and recommend my friends and family. Good selection of cars to choose from.

I have owned my Terrain for 3 months now, and am absolutely in love with it. Super smooth, great pick up, and I get a lot of complements on both the exterior and interior design. I average 26.3 MPG city and highway combined, which is not bad considering I live in Florida so my AC is never off in the car.

This is my first suv and I was overwhelmed with the style and performance. I have been purchasing General Motor vehicles for a long time. GMC terrain sle is a outstanding investment. I'm enjoying my retirement and my new GMC 👶

Came in with no appointment, but was taken care of in a timely manner. Work performed while I waited in comfortable customer lounge. Had a cub of coffee.

This car is wayyyyyyyyyyyyyyyy better than i thought it would be! It is beautiful, tinted and very comfortable!!! i wont ie i look good riding in my baby

I been coming to this guys for couple years now. They never let me down. We as a family collectively bought 3 cars here and each time they helped us out. My sales and finance reps where Marlene and Teo. Super happy.

Its a decent car, but on a car frame. I had a GMC Envoy a truck frame SUV and it was so much nicer to sit higher than the sedans and baby SUVs on the road. Doe have nice accelerations and mileage tho.

Very happy... will buy from there again when it's time to purchase another car

I've had mine for 4 years 2016 SLT ,traded my wife's Hyundai Santa Fe for a caddy srx which I drive as well as a 2018 GMC 1500. The Acadia has been super reliable .knock on wood.. just basic maintenance

I have had this car 5 years 90000 km. No problems so far, it has been exceptionally good. The only money I have spent is gas and oil changes. I. Would buy another one
