I'd argue my experience here was more like a 3.
I'd argue my experience here was more like a 3.5 than a four, but it wasn't too bad. Of course there was the typical salesman crap you'd expect, even if you're just in the looking phase. But overall the dealership was clean and well kept, and other times I've been to this dealership for service they have been professional. But I have not bought from them. Even though my one experience looking at cars here was average, all things considered I'd say this is a good place.

I have purchased cars from Sewell in the past and once
I have purchased cars from Sewell in the past and once again, their service and inventory is SUPERIOR! We are so happy with our vehicle and the overall experience!
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

The best used car deal I have ever made.
The best used car deal I have ever made. First time buying with Sewell and had a great experience.
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.
