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!

Mach-E from Phil long Ford Denver
I ordered from this dealer, even though it's 45 miles from me because the sale rep knew the Mach-E very well and had a car I could drive. Ford dealers closer to me were clueless if not down right stupid when it came to the full electric Mach-E. A few glitches on the delivery but over all a very good job by the sales person Brandon. Great ride!

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

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!

Austin Ellenberg helped us find the exact Buick Enclave
Austin Ellenberg helped us find the exact Buick Enclave that we wanted. He was very nice to work with and patiently helped us understand all the new features on the 2025 car. His explanations of everything were excellent, and we appreciate his offer to talk with us again about any new questions that we come up with. We also appreciate that he had a new battery installed before we took possession of the car, since the previous extreme cold temperatures had run down the battery while the car was on the lot.

Great vehicle for traveling. Plenty of room for luggage and a small dog.. Very comfortable, The only thing I don't like are the vertical AC vents. I would like to see them be able to swing wider both horizontally and vertically.Plus my used vehicle had Onstar at one time and I can't cancel it off my car so that my calls always seem to go to Onstar at least once.

Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

You guys were great, easy process. Was needing to replace a service truck, and these guys were awesome. They made everything easy, and the process was smooth.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

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.

New purchase of 2019 Discovery Land Rover
My last car purchase was for a 2006 Mazda, still have it, did not trade it NEVER had a problem with it BUT it was time for my luxury vehicle. John, Kyle, and team took great care of me. This could have been a very stressful event but it was not. They made the entire process from scheduling, test driving and purchasing very easy!!

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Just the right size for 2 adults, a child, two large dogs and two large ice chests to head to the boat with all our equipment and food. Hated to see them downsize it in '17. It has had few maintenance issues and they have been reasonable in cost. It has kept it's value over the years.
