I was thinking no all along, then I saw the lottery part.... LOLOLO Oh my GAWD no!!!

First I was thinking that if you ask them to pay for one oil change (because you WILL need one after the miles put on the car from the trip) and they pay for one week's car payment (since they are driving it while you're still making payments) and they completely wash, vacuum, and clean it out after they return.... they'd realize a rental is the same cost!
