Will definitely be using a Sewell dealership again in the future. No hidden fees, straightforward. Great to deal with. Highly recommend!
This is a luxury suv with plenty of room.
This is a luxury suv with plenty of room. I'm still learning the features. It is a smooth ride with a great interior. Great for towing a popup camper.

Enjoying my new Volvo
I appreciate Daniel for his customer-oriented approach to sales. No pressure. Asked and noted what I was looking for. Did not try to talk me into something else. Took the time to listen!!
Updated model
Read many reviews and researched this vehicle and that helped me decide on this vehicle. Traded in a older suburban for this updated Yukon. Look forward to driving it.

2021 Yukon XL Denali Diesel 3.0
This Yukon XL has exceeded our expectations. We upgraded from a 2014 XL and it's like apples and oranges. From a size standpoint, the new design allows my 6'6 son to sit in the 3rd row. Not possible on the 2014 xl. Also, they have upgraded all of the finishes and with the new 10 speed tranny the XL drives and feels amazing. We also opted for the 3.0 diesel as that's what was available. We didn't even test drive one as they are hard to find - but man are we happy with the engine, gas mileage, and just how quiet it is. In city driving we're getting about 22 mpg, and then on highway expect to get about 27. Safety features and heads up display all work great. And, the sunroof thing is amazingly huge. Well done GMC and I highly recommend the Yukon XL to anyone that needs to move people in comfort. :)

Working with Steven was great!
Working with Steven was great! I felt comfortable and welcome through the whole process. Steven was very kind and professional and not pushy like other dealerships. I would definitely recommend Family and friends to shop here.
Beautiful riding truck
Love the truck, lots of bells and whistles, smooth ride, satin Steele is a beautiful color. The Denali has lots of space for my four boys.

Our buying experience with Kevin Baldwin at Prospect Ford
Our buying experience with Kevin Baldwin at Prospect Ford was excellent! The truck we were interested in at Prospect was 3 & 1/2 hours drive from us so Kevin sent a detailed video of it which sold us on it. They negotiated a bit on the price & I drove away happy! Definitely worth the drive! Thank you Kevin & Nick

First time customer in Dallas, Tx
For some reason Mark's name is not on the list where it says, "Choose their name," but Mark was so helpful, patient, explained the process clearly and was very professional. I highly recommend him and would work with him and his team again. I would hope for a promotion for him Hyundai. :)

My purchase experience of a Porsche Cayman was first
My purchase experience of a Porsche Cayman was first rate. Andrew, my sales assistant was most helpful in every way to make buying from WAG a pleasure. Shaun, the GM met my asking price on my trade in and moved the process along quickly. Erik, processed the paper work without any effort to sell me any extra plans. I bought a great Porsche at a price that was below market value. I know you will be well treated, as I was, by this team of professionals. Do what I did, get beyond the reviews and go in and meet these people and I bet you will be glad you did! Jeff K

Sewell Cadilac of Dallas was Outstanding.
Sewell Cadilac of Dallas was Outstanding. They treated us like an old friend. The whole experience was pleasurable and quickly handled over the phone. All of the details and paperwork was done when we arrived. They took time to explain all of the new vehicle's controls, features and warranty issues. It took about 5 minutes to sign the paperwork on the purchase and we were on our way. i
