I love the 99-01 Cobras except for the IRS.
i almost bought an 'o1 cobra because of (among other things) the IRS, i love it. since my mustang is my dd i would kill for an IRS!!
as stated before, if you can get past the color (i couldn't, i hate white cars) then go for it, cobras are nice rides and compared to a 97 gt convertible it should feel a little quicker
