Worked with both MATTS they came to what I wanted for a payment. It was all done without going to dealership and that saved a lot of time. They were very professional, helpful and courteous though the whole process. The finance dept was smooth and explained all the paperwork for a fast transaction. I leased three vehicles from the new owners and will go back for my fourth. THANKS FOR ALL YOUR GREAT HELP.

Matt at Tim's truck capital was awesome to work with. He answered all my questions and was willing to work with me being an out of state purchase. I found a truck in state instead, but I'd definitely work with Matt again if I need another work truck. Great business with a great selection of trucks

Pleasant experience!
I found the elusive trim level of Jeep I wanted here and was unsure of how negotiations would go. I was more than satisfied with every aspect of my purchasing experience. My salesperson Johnny was extremely knowledgeable and the sales manager Jim was incredibly flexible. The whole process was low stress and I left with my dream Grand Cherokee. Thanks Key Auto!
