there are always ways to con a salesman into giving you a test drive
just go in with a nice new car like a new 4 runner or heavily modded car (bodykit etc.) it will look like either you or your parents have a lot of money and are itching to spend it
act really interested and work out financing plans and say somthing along the lines of "i am lookin for a new Summer or winter car" also say that your parents are going to buy it for you as a university gift
these methods will get you a test drive
