Ask for Joey! He is the best sales person I’ve ever dealt with when buying a vehicle. From that time my husband and I walked in the dealership l, almost 2 months ago, until now he’s been great! We had some hiccups but they were all beyond his control. He went above and beyond for us even when he didn’t have to!
