Never been worried about putting mileage on my cars. As I once heard someone say , "too many people worry too much about the NEXT owner of their car."

As for gasoline, I have often had months go by and not drive the vettes. They still run fine even sitting for so long, and so far have not seen any damage caused by the older gasoline sitting in the tanks.

I think the gas systems are sealed up pretty well, so I don't think I would worry a whole lot about evaporation being a big problem. Not unless you plan on letting the car sit for years, I guess. And if that were the case, unless it's an immediate collectible, you might as well sell it and buy something you aren't worried about driving as much as you want.
