Ferrari Mondial (any running model before the T with semi decent service records), Acura NSX, Lotus Esprit (a decently sorted 87 or up), Nissan Skyline GTR (r32's are being imported now, r33 are coming in a couple years), a good unmolested MkIV Toyota Supra Twin Turbo (getting very difficult to find one that hasn't been modified, and they can go way over $30k).
