Great experience!
Recently bought a Mazda CX5 Grand Touring here. The Salesman, Bob Burger is simply awesome. The car was cleaner than the dozen we looked at, and the 1/2 dozen we test drove in the past month. Very happy with the purchase, and our experience with this dealership. I wouldn't hesitate buying another vehicle from them.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Interesting but good
So the car had cosmetic damage and they tried to sell it as is as I was like no I’m not buying it like that so they “fixed” it super fast but not really and I said no I’m not buying it like that so they fixed it for real and then I bought it. So props to them for fixing it appropriately but it just took hours to do it the way it should but shame on them for trying to get me to buy it as is. They were nice the whole time though. Easy to work with.

This dealership has an impressive slate of exotic cars, I was just looking for a lesser jag. They treated me very well not pushy and very helpful. There were no hassles in getting to test drive the car I was looking at. When I decided to walk away there was no pushback or pressure to “ run the numbers”. Both the sales person and the manager communicate with me to ensure my experience was a positive one.

Message sent directly to salesperson: Hanna, I will be recommending YOU whenever I know of someone looking for a vehicle. When someone is making a major purchase, like buying a car, it is so important to have a sales person with genuine integrity and relentless focus on the customer. Your communication throughout the process has been stellar; always keeping me updated. I appreciated that you not only focused on the sale, but also on doing proactive work to facilitate a smooth transaction on a specific day, with my family's needs in mind. That 'extra' means a lot!

Amazing service from entire team
Late review, We bought a Jeep Cherokee Latitude from this dealership this summer. The Salesman Adam, and Service manager were outstanding! Test drive vehicle (unfortunately on a rainy day) didnt hear or discover any issues. Took car home and next day discovered very noisy road noise and undefined noise from front of vehicle. Working with the team to discover the problem althought time consuming was a far more pleasant situation than expected. The entire time the team worked on the issue provided constant interaction, communication and updates. Just wanted to assure the team that I was completely happy and AMAZED that the situation was taken care of professionally. Thank You Gary Gregory

Overall, friendly and trustworthy staff
I travelled out of state for my purchase and Brad did a great job at answering my multitude of questions! They had a driver pick us up at the airport(1 hour away), washed and filled up the car. Brad sat down with us helped us find some local eats and got us convict way with ease. Paperwork was quick as well. I can't thank them enough for making this car buying experience very productive and hassle free! Thanks again Brad!
