Had a very good experience.
Had a very good experience. Julio, our salesperson, was very personable and didn’t pressure at all. If I had it to do again I probably wouldn’t have purchased the extended warranty. I did find a problem with the passenger side sun visor but we will see if they can help me out with it. I love the vehicle.
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.

I've dealt with better.
I've dealt with better. Not completely negative of an experience. Not the best either. Their service dept seems to be slacking. How do you put a car on a lot for sale with a check engine light on? I can see when it was last cleared. Not very long before I bought it. Salesman trying to tell me the engine isn't getting up to temp because it's cold outside. No. It's a bad thermostat. Headlight wasn't plugged in. And WAAAAY out of alignment. Their cars are supposedly looked over with a xx point safety check. I doubt that. Looked over, cleared codes, topped up fluids. Put an oil change sticker on the window. But did they really? It looks clean so I assume so. The detailers did a FANTASTIC job!! This car was super clean!!

YOU GUYS ROCK!!
I walked in and was immediately greeted. The guy that helped me had very great customer service skills and was very friendly. I have a crystler 300 and the oil needed changed and transmission fluid checked. I was expecting to pay around $250-300 bucks but got a discounted price and only paid $165. I definitely will be going back when service to my vehicle is needed again

My review is for Jimmy Carpenter specifically!
My review is for Jimmy Carpenter specifically! Let me just say, I am always wary with buying a new car / working with a dealership. I feel like they always try to upsell you and make the most money off of you - which to an extend I completely understand, it is a business after all. However, Jimmy I believe truly had our best interest at heart trying to work out a deal. He worked with us and tried and tried to get us our dream car, gave me advice on how to get the most for our trade ins, and I truly believe he wanted the best for us. I really hope to work with him in the future, and I would recommend Jimmy to anyone needing a car. I don't believe it is the norm to say you trust the person selling you a car, but I really did! Jimmy was so transparent, kind, and understanding on what we needed and what he could do for us and I truly appreciated it.
