The experience was amazing. My husband and I walked around for a few and here came Patrick the amazing car salesmen with a wonderful approach my question to him was are you ready to sell a car. He made the experience easy. He helped us pick the car that fit right for our needs. he was friendly honest and most importantly he saved us money . I’d recommend you guys go check him out.

Love this place!!!!
Really enjoyed this car buying experience. When the car started acting up they were all over it and fo t it to a Ford dealership for diagnostics. Literally refused to let them send the car back until they were satisfied that my car is tip top. Can't say enough about Dave in sales, Phil their awesome mechanic who advocated for me like it was his own car. Then the GM met with me to talk about the experience and stand behind the car if the same problem recurs. Jessica at the desk made a rough week much nicer. So pleased to work with Blasius of Middletown and will be a repeat customer for sure!!

I had my 2020 Terrain for 5 years before I had any major issues out of it. My brake booster needed replaced. After about a month of it being out the shop someone hit and totaled it. Very sad day. I love my Terrain

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.

2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

My 2016 GMC Sierra 1500 SLT All Terrain - Love it!
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.

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!

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.

Love love LOVE
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.

Lou was my salesperson and he was super communicative,
Lou was my salesperson and he was super communicative, explaining and re-explaining when he seemed to feel it was needed. No surprises along the way, I was able to test drive the van as much or as long as I wanted, have a mechanic come by to inspect it and they washed it and added a full tank of gas on pickup day. They had done some quality servicing to the vehicle as well before pickup day. Lou mentioned early on that he wasn't paid on a commission basis, which was a good detail for me to know. In the end, all the numbers were the same from the beginning to end, no "uh oh" moments and it was a super fast experience on pickup day - probably the fastest ever for me to get the keys and drive a new (to me) vehicle home. I will look to use them again if possible in the next year or so. Highly recommend.
Beautiful!
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

Old lady in need of a vehicle!
Today, purchased the 2013 Nissan Juke, 112,600 mile for $9,995 today. It will be ready Wednesday or Thursday this coming week. My sales person Amy was excellent. She knew I had a firm budget (retired) and she found two great vehicles to test. The Jeep I could have taken home today with less milage... a little older, however, Jeep mph versus the Juke..., Nissan won even with higher mileage. So far, I'm "a HAPPY CAMPER"! I can't foresee any problems from now until pick-up. So, I'd say, if you need a reliable used car, Amy is knowledgeable and, in spite of the packed waiting room with eager customers, we were never abandoned. Note; yes, the sales people had to multi-task at times. Understand, at these reduced prices, compared to any dealerships for used cars... Patience, just a little patience - and you'll be treated right too. All the best to customers in need of a new used vehicle!
Failed transmission and full replacement
We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

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!

a place to go for bargains if you have patience
Alex excellent salesperson very patience and honest. The dealership is another story, if your looking for a reasonable price this is the dealership for you, they get cars from Auction so no idea about the history of the car, they get checked when you already signed for the As- is purchase, don't go there on a weekend, if you have patience, wants a bargain, (non negotiable deals)time, and good mechanic this is a place to go, got lucky with Alex very accommodating and great salesman

Fast and dirty.
Fast and dirty. 20+ salesmen all busy. 800 used cars from auction, none of them have been detailed yet. If you need a car today on a sub $15k budget I would go here and detail it yourself. Good place to buy a first car. Don’t buy a luxury item or anything collectible. The the inventory doesn’t turn super fast so every single car will likely need a rotor resurfacing. They had family guy on the tv which I thought was odd for a dealership. Not really dealership vibes, which is good!
Very nice little SUV
Been really enjoying it! It’s actually very comfortable car and reliable! Ride is smooth and quite! Efficient fuel economy is pretty good! I love it!
