best price and selection in one place
Great customer service and bide variety of selections. I found their price is lower than other dealerships. There is no hidden fee and sales people very straightforward. I would highly recommend this place.
Good car.
Bought 2012 in 2021. I have put 18,000 miles on it. Had to do brakes, CV joint, and the thermostat. Otherwise, it runs very good.

2015 GMC Terrain Review – Reliable and Comfortable
2015 GMC Terrain Review – Reliable and Comfortable SUV: I purchased the 2015 GMC Terrain as a reliable daily drive, and it has exceeded my expectations in many ways. The interior is spacious and comfortable, with high-quality materials that give it a premium feel. The seats are well-padded, making long drives enjoyable. In terms of performance, the Terrain delivers a smooth and stable ride, with responsive acceleration that meets my needs. The fuel efficiency is reasonable, which helps with long commutes. The exterior design is bold and distinctive, giving it a strong road presence. Reliability has been solid, with minimal mechanical issues over the years. Maintenance has been straightforward, and the vehicle has held up well. Additionally, my purchase experience was fantastic, thanks to Claudia Reid/Sales. She truly took the time to negotiate pricing and ensure I got the best deal possible. Her dedication and professionalism made the entire process seamless. Overall, the 2015 GMC Terrain is a great choice for anyone looking for a comfortable, spacious, and dependable SUV. Would I recommend it? Yes, especially for families or commuters seeking a balanced vehicle. Thank you, Auto Club of Edison!

I like the back up camera inside the rear view mir
Test drive before you buy.....so far it's good but it's expensive for gas to fill up was $70. And city plates is $301 and also the car is heavier than the ford explorer that's why everything is so expensive

My Work horse.
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.

Great Dealership!
I came in, as a first time buyer and everyone was so nice and helpful. I was shopping for a used car and the process went so smoothly and way easier than I thought it would. The car is used but in very good condition. Most importantly I didn't spend all day in a dealership. I will definitely recommend to friends and family.
check the oil every tank fill, dealer advised if it
check the oil every tank fill, dealer advised if it dropped too far it would scrap the timing chain, interference engine lock up. a 6 inch strip of paint blistered off the roof, the rear deck won't set down horizontal (everything slides to the rear. rides like a limo, handles like a dream, no real probs. 168k on the odo.

An AWESOME Vehicle!
This wasn't the vehicle I'd gone to the lot to see... But it was parked 2 vehicles down, and the price was $3000 cheaper!! It even has more bells and whistles than the Toyota I'd initially planned on getting. Awesomeness!!

Professional staff
First time car financing, Drivetime "Union City" made this a great experience. The application process was quick, and I received a good price for my trade-in. Every vehicle on the lot displayed the year & price clearly. The lot was clean and easy to drive around. The building was clean inside, the staff very helpful, friendly and knowledgeable.

The people here were an absolute pleasure to do business
The people here were an absolute pleasure to do business with!!! They worked hard to earn my business and met my offered price. In fact, they came in LOWER than my offer by $500! Sunny Rohra was my salesperson and he took EXCELLENT care of me. Between coffee, cookies, jokes, small talk and getting me the best possible deal, I was VERY satisfied! Paul Mitchell in the Finance Dept was TERRIFIC!! I was in and out of there in 10 minutes! And Alex, the tech guy, was VERY helpful and patient. Overall, my experience was great. I would HIGHLY recommend Butler Lexus of South Atlanta! There were several Lexus dealers in my area, but being that they were unwilling to work with me, I made the hour long trip down to Butler and don't regret it one bit!
Oil pan issues with my Acadia

This was an online purchase with salesman Roq Micheal’s.
This was an online purchase with salesman Roq Micheal’s. He was very helpful and made this online deal flawless. Reached a purchase price with Jonathan and felt confident to put down a $1000 over the phone. We had already did test drives in Chattanooga TN. ALM couldn’t even be beat even by Marshall Mize Ford. Great job ROQ.
Reliable and comfortable.
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.

Great buying experience.
Great buying experience. Buying process was easy and the staff was friendly and courteous. They made everything seamless and help me surprised my son with is brand new car.
Good car only some issues
Have had lots of problems with the wheel sensors. New tires and new sensors and still have the same issue. Shows tire low and it is not. Just car not even two years the air conditioning would not blow out cold air. The compressor in the back went out, need to be replaced. Side car waring lights come on sometimes even though no car anywhere near me. Fold in mirrors are a joke the driver side comes in and out, however the passenger side sticks. Dealer said yeah that happens. This car is garage kept!
