Where to rent a Mustang?

OK please excuse me if this has been covered before, but I did a search and couldn't really come up with an answer.

Is there anyone else other than Hertz that rents Mustangs? I don't need to have the GT 350 H, a base Mustang will do. I want it for my next car, but would like to sell the wife on it too and I figure if we can rent one for the weekend for an upcoming trip it would kill two birds with one stone.

Issue is, Hertz wont let me pick up in Philly and return to BWI. Was hoping someone else rented Mustangs but so far I cant find anyone that has anything other than the GM crap boxes that have seemed to keep GM alive due to the rental car market.

Thanks!

Do you think a local Ford dealer would let me rent it in Philly and drop it off in Baltimore?

THAT is the whole problem. I can rent a Mustang from Hertz with no problem, they just wont let me drop it off somewhere other than the pick up point.
