My collection is similar to wild Bill's - a white '57 T'Bird, and a "K" code '65 GT Mustang convertible. My Mustang runs in "stealth" mode - all of the Shelby suspension mods (including steering, brakes, T-Bars, Koni's, braces, etc.) but nothing on the outside but a "stock" look. Even painted the Koni's black and installed taller front springs so as not to give away the lowered upper control arms.
Sitting outside in the weather is a really sweet "10th Anniversary Model" 1999 Mazda Miata convertible. The 1985 ASC McLaren Capri convertible that my Dad bought new had to go to make room for the T'Bird (I'm sure Dad would understand - I sold it to my Brother, so it's still in the family). As you can see, I'm a ragtop kinda guy.
