Jose and the gentlemen who ran the numbers were absolutely amazing. My finance lady was so beyond amazing. They all were great and i had such a better time buying a brand new car then i thought it would be for my first time. Absolutely had an above and beyond type of experience. I'm so thrilled with my purchase and how the process went.

Foundation Chevrolet review
I had a great experience with Foundation Chevrolet. As soon I found my dream car, I got connected with the staff and I booked test drive next day. As soon I arrived I got a warm welcome from everyone there and it didn’t take longer to finished all the necessary paperwork and got my new cat keys. I highly recommend Foundation Chevrolet.

HUGE selection of cars. They have a row of just luxury and sport cars. The prices may be a little bit on the upper end, but overall a great dealership.

Purchased a dodge challenger here recently. I had been researching for a while so I knew the value of the car. When I found this one I thought it was a fair price. Christal did a good job with the transaction. I’d do business here again in the future

Berkenkotter Motors ParkerReviews
Berkenkotter Motors Parker review
I toggled between 4&5 stars and I landed on 5 (which is hard to do with me)and I will tell you why.I started out with BMotors over a month ago looking at one particular 5th wheel and after it had been listed that it had some things that worked it actually didnt but well my son was a used car dealer for many years and this was the reason I asked for it to be checked.I know how things work in used vehicles its not always obvious even to the dealerships. They could have sold me it as it was but they were 100% honest and said they needed to put me in another trailer.This is the most important aspect of a dealership really. You get what they are saying! This new 5th wheel is more then double the price but its more then worth it and I am satisfied with it They did good by me and in house financed me on top of it. Bret was amazing and answered every time I text him a question or concern. When I was ready to haul this giant 5th wheel for the very first time with a truck I just purchased they actually had their service guy (and another employee follow)drive about 6 miles with me to get me out of the city and show me how to make the turns and show me how to use the brake system on the trailer.This is above and beyond!! This Yall is a 5 star Dealership!!! I highly recommend Berkenkotter!! Go see Bret, Alen or Any of the Guys they eill hook you up!
