No offense or anything, but do you guys really think that a non-GN Turbo Regal is really a sleeper?
These cars have been around for soooo long that they've all pretty much proven themselves as straight-line performers--GN's and T's. Almost all car buffs I know what a T-type is (Mustang owners too). "Ricers" are car buffs too, however their taste and judgement may not be in agreement with those of the "old school".
Unlike a sleeper, the T's do have some nice wheels on them. Throw some wire wheel covers and a set of whitewalls on, you have a different story--but now you not only have a sleeper, but also one ugly ride.
If anything, the misconceptions of how powerful GN's and T's run rampant. I've had people ask me if I run 10's with my relatively-stock GN!
My personal favorites are the 1986 GN (mine) and the Midnight Blue T-Type.
