I have the two listed below, my '84 is soon destined to supply parts for the '89 GT and then volunteer it to a "recycling yard".
But i've had good times with both cars and done many a hellacious burnout with the '84 LX. My GT i will be keeping for at least a couple of years until i'm out of school, then i'm either going to keep it as a street/strip drag car or try to sell it to get another 'stang!

Mustang Parts Specialties ripped me off, it could happen to you as well.
