READ the fine print of the lease agreement. If it is not spelled out what can and can not be done to the car, then its a "gray" issue, no?

And yes, a dealer/bank/manufacturer wants the car returned EXACTLY as it was leased to you. So, if you put on a body kit, special wheels, blah blah, be prepared to remove all items. If, for some reason the dealer doesn't notice these things, you will NOT be compensated for them.

A leased vehicle does NOT need to be serviced at the dealer where the lease originates. (ie, what if you move out of state - you would be expected to return just for service, correct?) so, just because "your" dealer may be agreeable to some modifications, doesn't mean ALL dealers will be, which may cause warranty issues down the road.

Remember the basic of a lease is you do NOT OWN the car. It belongs to the leasing company. You are essentially a "renter" for x months. At the end of the lease you will be required to have the car inspected by the local dealer/appraiser service. They will not every change/defect (ie, worn out tires, paint scratches, dents etc.). Leasing companies long ago got wind of the abuses people would commit and try to get away with. They will charge you accordingly for not returning the car in "like new" condition.
