Awesome buying experience
Very good buying experience. We purchased a BMW with the help of Phil. Both Phil and the rest of the staff were always very friendly throughout the buying process and we never felt pressured to buy the vehicle. We were able to test drive the car by ourself and more than one time before buying.
This truck has a jerk when changing gears sometimes.

Pleasant experience purchasing the car.
Pleasant experience purchasing the car. Didn?t feel pressured like some dealerships. They gave a very fair trade in price for our current car. Took the time to explain all the technology and answered any questions we had. They followed up after the sale to see if everything went smoothly. Overall very happy with the purchase experience as well as the car.

One of the best buying experience I’ve had in a long
One of the best buying experience I’ve had in a long while. Jeffrey was great. Had everything prepared for our appointment. The truck was cleaned up and ready for the test drive. Once we got back we worked on the numbers. They were close, but working with the sales manager we agreed on a very fair deal. And that’s what I appreciated the most let’s be fair with each other. The next day working with Preston in finance was also very pleasant, he worked his magic and got us a great rate with the bank. Overall experience was excellent! I hope I won’t need another truck for while, but if I do I hope the three guys are still working here. Cheers to them. Ask for Jeffery(sales).
