Recently purchased a Durango Hellcat having come from out
Recently purchased a Durango Hellcat having come from out of town to do so. Our salesman Taylor and literally everyone else we dealt with there were superb!! They were helpful, attentive to our concerns, and delivered an excellent result for us at all points in the purchase process. I thank them each and all and would be pleased to do business with them again!
This truck has a jerk when changing gears sometimes.

Ladies shop here!
Ladies, ask for Jimmy Briseno! For the FIRST TIME we found a salesman who answered MY questions and catered to ME when buying a car! The minute my husband told him it would be my car Jimmy went above and beyond to show me multiple options, all while really listening to what I liked/disliked about each car I test drove. He was patient without being pushy and didn't treat me like I was silly just because I'm female--absolutely recommend!
2021 GMC Sierra Denali
This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

I am giving this a five because Carla was so good to work
I am giving this a five because Carla was so good to work with. The 2016 Forester was not a good experience. It road really rough and my wife hurt her back on the test drive. The radio did not work and the navigation system failed about halfway through the test drive. So, to sum it up. Our sales rep, Carla was great and the experience at the dealership was good, but the car we went to look at was kind of a disaster.

Seems to be a decent dealer.
Seems to be a decent dealer. Sales people are respectful. I'm trying to negotiate on a new 2023 Ford F-350 4X4 with 7.3 gas V8 and they seem to be a bit reluctant to bite on what I consider to be a fair OTD offer, especially since the vehicle may be subject to some lot rot due to the length of time there on the lot and not sold as of yet.

Thank you to Cynthia McCoy
Thank you to Cynthia McCoy for making my car buying experience exceptional. Her knowledge of the process was very inspiring. From the beginning to the end. The test driving of various SUV’s, the options, the answering of questions, etc. I’m reminded of one of my favorite quotes. It’s not all the time what a person does, it’s how they make you feel. I got that feeling with Cynthia McCoy.
