Got a used car.
Got a used car. Had issue. Fixed with a 0 hassle. I gave them 5 star. Above an beyond. Its after the sale that matters.

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

Just purchased/leased a 2026 Trailblazer.
Just purchased/leased a 2026 Trailblazer. Stanley Thornton was the AutoPlex rep. Very knowledgeable about the brand, including pros and cons. His communication skills are extraordinary. His dedication stems, in my estimation, from his veteran background. solid character, give him a call !!! Dayne Luce.

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

I have bought my last few Subarus from this dealership
I have bought my last few Subarus from this dealership even though it is further from my home than at least 3 other Subaru dealers. They always seem willing to make me a nice deal on a new car, and they go above and beyond making the the process fast and convenient. Further, the sales representative with whom I worked, Reid Stanley, was accommodating, calm, not pushy, helpful and informative. Really everything one would wish for in a sales associate.
Overall I am very happy with my new Truck.
Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Everyone was very helpful and kind. I requested scratch repairs on my purchase and it was completely taken care of as discussed. Salesman was very nice and no pressure!
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.

Honest, friendly, experienced staff.
Honest, friendly, experienced staff. Worked with Landon, Connor and D. They did a great job and worked hard to gather details for me and keep me informed. The lobby is nothing special and don't expect anything for free. Negotiations were straight forward, no silly games on the used vehicle sale. Didnt get everything I was promised (Call back, delivery, gas card, other details) but it was good enough. Thank you!

I went in knowing exactly what car I wanted to test drive
I went in knowing exactly what car I wanted to test drive and had an appointment with Jean (John) Venant on December 27th. The car (2024 Mazda CX-5) was waiting for me when we arrived. Our salesman was a great guy & seemed knowledgeable about my particular vehicle. It didn't take me long to decide to buy the car on the spot. Baltimore in the financing department fought very hard to get me the best rate/deal available. They even gave me far more for my trade in that I was anticipating. Everyone throughout the (seemingly painless) process was great to work with. We felt very valued. My only "complaint" is the sticker shock I had when I saw all the "dealer fees" on the bill of sale. Many things (window tint, fabric protector, etc) were all things that you only typically see when buying a brand new car and not when buying a used car. And, with any used car purchase, I made sure to get the extended warranty. That's just smart no matter which dealership you buy from. However, I am concerned a bit to read very mixed reviews of the EasyCare warranty company, as it seems they only approve HALF of the claims submitted. Fingers crossed.
