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. :)

Great purchase experience!
Just had a great experience with the purchase of an excellent Ford 150 from David "The Car Man" Mitchell today. He was very helpful and super efficient with all that went into my complicated deal. I would highly recommend checking him out when you need quality vehicle.

Transparent, fair and easy. Joe was very accommodating with test drives and answered all of my questions. We were never pressured during our visits. We have purchased two cars this year and both times the experience was great and the cars are very clean. Kudos to the detail center. Nate also was very helpful and thorough with the financing and extended warranty paperwork.

While the initial reason for my visit was trying due to seizing a motor in such a new vehicle the service staff was incredible. My service advisor Kelvyn was a standout and exceptional. He kept me apprised every step of the way and due to my unique situation he was instrumental getting me back on the road. As a business owner myself, I'd love a few more Kelvyn's on my staff!!

I'm a car dealer skeptic and relentless researcher--the kind of person who turns over every stone on a big purchase. This dealership was a breath of fresh air for someone like me, seeking a fair, friendly, and honest place to buy a new car. Integrity goes a long way when it comes to someone helping me with a purchase I'll be committed to for six years of financing--and they've got it in spades. I had the pleasure of working with Michael Jorgensen, Javier Vega, and Mikel Najar, who, at every step of the process, not only made sure I never felt pressured but also left me feeling fully prepared and well-advised. The deal I received was so competitive that I flew all the way from California to get it. They even picked me up from the airport--something not even some of my closest friends would volunteer for. If you put them in a position to compete with another dealership's offer, more often than not, they'll match it (or probably beat it). When I arrived, the hospitality was second to none. Everything we agreed upon was upheld, and topics like extended warranties were communicated in a way that felt more like sincere guidance than a sales pitch, tailored to my specific needs. After a long flight their pop-up coffee shop was a very welcome addition to my visit. Every single person I interacted with was a pleasure to speak to, and I genuinely mean that. They clearly take care when hiring good people, and reviews like this are the result of that effort. Bravo, Toyota of Cedar Park--you turned a car dealership skeptic into a believer (and a first-time Toyota owner).
