very clean inviting place.
very clean inviting place. The manager lady greeted us when we arrived, we were attended immediately by a very polite young salesman. Only disappointing thing was that we were given a written % rate and when we finished the deal the person that does all the finishing paper work, I believe the finance manager, had a higher interest rate, I was upset about that but I really wanted to get the vehicle, as a birthday present and did not want to do it all over because my credit score was already pulled and I wanted to give the surprise to my wife.
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.

Bought a 2024 Tucson SEL.
Bought a 2024 Tucson SEL. Overall I love it. I’ve noticed in the less than two weeks I’ve owned it a couple of flaws. The automatic RADIO volume adjustment does not appear to work. And more problematic and safety oriented is the driver side sun visor. It is not the expandable (slider) variety. So you have to take your eyes off of traffic and duck your head to push it to the driver side window. NOT GOOD.

I reached out via cars .
I reached out via cars .com about a specific car that I seen on their website. I got a response the same day. It was by a gentleman whos name is Joe at Winter Park auto exchange. He took some video of the car i was curious about. I went a few days later to actually check it out, with my wife. Car was exactly as advertised, clean low miles. So the purchase was lightning fast. I test drove it and did all the necessary paperwork in probably 30 minutes. They have a lot of inventory. If your in the market, please check them out. Great people!!!
