Test Driving Warehouse Vehicles

There has been a feedback post made about this before but i feel like it needs more attention.

There is a lot of cars available from the warehouse can we please get to test drive stuff before we have to get it imported by a car dealer to then not like it 

It would be something as simple as paying 'x' amount of cash to test drive it around an instanced area or some kind of track and if you return the car without destroying it you get your deposit back.

Is there any reason as to why this a bad idea or can't happen please let me know.
