Great experience and customer service
We had a great no-haggle experience with this dealer. They’re very accommodating, addressed all concerns, and have been attentive any time we needed assistance. Great people!
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.

Went in looking, came out driving
Went in just looking and were offered a deal we couldn’t refuse. Joe was very personable and treated us like people rather than a quota filler.

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

Mat Piner was a very kind and personable sales man
Over all experience with Mat and Ray was great The GM of sales not so good Thought was at a party in the sales room when trying to finish the deal with Ray Mat was great through it all him and Ray apologized many time for the bad experience I had with GM of sales Thank You Mat for being so kind and understanding Recommend the dealer not the GM of sales
Our AT4X has been an excellent mid-size truck.
Our AT4X has been an excellent mid-size truck. The ride is shockingly smooth and the engine has a lot of torque. Wish the interior had less plastic and GM's failure to have a rear view camera mirror or controls for garage/gate contols is inexcusible. Overall, could not be more pleased with this truck.

2024 GMC 3500HD AT4
This review is for a two week old truck. I have been trying to get a 3500HD AT4, gas engine, 8 foot bed, 5th wheel prep, in blue for over a year (almost 2). My dealer finally received an allocation and I was off for the build!! However, when my build order was sent to me the color had defaulted to black (blue was discontinued for 2024) and the only way to change it was to cancel and start over.....so black it is!! The truck is gorgeous and much larger than I thought! I am pleased with both exterior styling and the 2024 interior refesh. My only complaint is the seats, they are a bit firm.....still comfy....but firm. The GM sunroof is small, so small I passed on the option. Mechanically this truck is a pretty sound design. Another 50hp for the 6.6L gas engine would be nice, but 401hp is pretty decent. A PTO offering in the up level trims would be nice, as would a larger/dual fuel tank option is needed (GM is the only one that doesn't offer one), and a factory level in the front, and while I am dreaming a front locking differential. GM could up thier paint game, when approaching 90k I expect better paint. Value wise it is as good if not better than the rest of the over priced trucks on the market. Rumor is 20K per unit on average goes to the UAW pension, that's why your 50k truck costs 70k. In closing I have zero regrets other than the color, but I needed it immediately so here I am.

Great Reliability
Great vehicle, 65,000 miles and not a single issue, hoping to get atleast another 100k miles out of it. Extremely reliable. A family member of mine bought a Honda that broke down at 16,000 miles and got stranded. Would absolutely recommend a 2018+ terrain

Great Dealership
Had a coupon for oil change and tire rotation. Always use this dealer for anything concerning my car. Never disappointed.
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.

2023 GMC Yukon XL Diesel is excellent
Ordered a 2023 GMC Yukon XL Denali Diesel 4 wheel drive in March of 2023. Took GM 5 months to pick up the order even though I adjusted a few minor options that were on constraint to have the order picked up (these were items I could purchase the parts and have the dealer install such as illuminated GMC emblem, Denali door sills, illuminated GMC cargo sill, cross rails for roof carrier). I wanted the diesel for the mileage and longevity. I am very satisfied with everything with the vehicle so far. Ordered the 20 inch rims/tires for a better ride. The ride quality is remarkable, so smooth. I drive a combination city/rural each day and I average 25 or more MPG. I have 9000 miles on it so far, and not one single issue with it. It is smooth, quiet, and and packed with technology. Goes through the snow with no problem. I have had 7 Suburbans, Yukon XL's and Escalades and in the past, full size Cadillac Broughams, and this is the best riding vehicle out of all of them. I am very satisfied. The only issue is the price has gone through the roof to purchase new. The Suburban and Yukon XL used to be more affordable new. My previous 2015 GMC Yukon XL Denali has an engine issue (camshaft issue even though the oil was changed at the dealer every 3K miles) at 165K miles and I had to trade it in quickly, so the dealer took it on trade when I ordered the 2023, and they wholesaled it. I was not going to buy another one with the 6.2 liter engine again.I really hope the diesel will go for many miles and years, and so far this vehicle has had no problems what so ever. Very glad I made the decision to try it again with the diesel engine this time. If the diesel was not available I would not have bought another GM full size SUV. Classic Painesville Ohio is the best to work with for sales, service and parts. They kept me posted throughout the purchase process and were very fair with the amount for the trade in and purchase price for the new vehicle.

Worth The Drive!
Getting the oil changed in Stryker's truck!! I am only his driver!! Feel free to BOOP that nose!!❤ So just GUESS who was the BIG hit at Boulevard Ford in Georgetown????? EVERYONE wanted to pet him. He strutted through the showroom with his eyes fixed on a new Expedition!! I told him mama can't afford a new vehicle!! Mama is an idiot, she forgot the wheel locks so they couldn't rotate my tires, but that's OK, we're going back tomorrow and Stryker will be THRILLED!!!! Thanks Skip and Shelly, for giving us a second chance, you're the BESTEST!!❤ Exactly why we don't go anywhere else for service!! Worth the drive EVERY time!! If I could figure a way to share a photo of us waiting in the lounge I would!!
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

This was the best experience in buying a car!!!
I visited the Preston Boulevard Ford of Lewes to see their 2022 Ford Escape. When I entered the store, Terry Spencer immediately asked if he could help me. I told him about the Iced Blue Silver Metallic SE I had researched online and he answered that he had one and would bring it out. Terry is very professional, knowledgeable, friendly, patient, Godly and a geat person. He spent a few hours with me going over the features of the car, taking a test drive, explaining features to me that I was unfamiliar with, discussing the Government 5-Star Safety Ratings, discussing the purchase and financing. The whole process was easy to understand and seamless because of his explanations. Terry answered all my questions and assisted me with the return of the Enterprise loaner car. He did all he could to help me. He could not have been more helpful!! Within a few days, I was the owner of a beautiful Iced Blue Silver Metallic Ford Escape SE. Thank you, Terry Spencer, for a job well done!!!
Purchased new in October 2024.
Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

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!

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.

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!
