go with the merc, especially if the ferrari is in marginal condition. it's a good deal only if you think it is. personally, getting a ferrari with curb rash and higher milage wouldn't be my dream, but then again, you're the one dropping all that cash on a ride. Which ever one you get, make sure to open up a savings account for the tickets you'll probably get. I went into my local stealership and they said I could get an M5 by the end of june if I wanted it. it's no ferrari or slr, but it'd be a great ride I think. I'm working that out in my mind, no matter how much car you get, $100K is still a lot of dough to drop! anyway, good luck with the choice and keep all of us posted!
