A few weeks ago at DCA when the weather was spectacular, they didn't have any problems giving me the Spyder upon request, when I booked full size (also while using the $30 off a 3 day rental coupon). I'm a First member, but don't know how much impact that had. If you're looking for a convertible that's overall pleasant, you're much better off with the Mustang. If you're looking to turn heads of everyone around, then the Spyder is the one for you... just depends on your desires.
