What BULL! Leave this dealer. Just imagine the crap you'd get from their service department.
As a few others have said don't buy from a dealer who takes you for a test drive in an unpreped car they are selling to a customer. Just think if they sold you a new car someone had hit too hard before it was broken in. A REAL dealer will use employee cars for test drives.
Actually I've given up on round the block test drives, not worthwhile. After picking a car I like I rent one for a few days and give it a real life test. Some dealers near me even lend out cars for a few days.
