"Reimbursement" - does that preclude "company script" in California? You will be counting the hours until you need to use it in the service department.

How to "spend" the certificate? Wait till that dealer is holding an event then round up 10 homeless people and take them in for a low buck widget shopping spree in the parts department and some free wine in the showroom

Who knows, one of them could be Nick Nolte and then buy a new Turbo Cab.

Pray the parts department has golf tees and paper towels in stock.

Overall its a stinkin deal Nick.
