you snooze you lose, shouldnt have sold your 86 back in the day. there are fewer and fewer left every year, buy something that your budget allows and modify it too your taste, or import and compliance one from japan (around $14,000 last time i got a quote).
xy falcons,mini's,chargers all cost alot more then they did back in the day, its the fans of the cars that make up the prices, majority of the time its the cars that people loved that go up in value. either you want the car or you dont, plenty of other cars that "handle" well.
