I had my '86 for 4 years, from '89 to '93.  So I don't think it had time for the turbocharger or transmission to crap out.
That car was totaled when I was hit from behind by a drunk driver.  I was stopped at a stoplight, late at night around 1 AM I think, and I saw headlights in my rearview mirror and the next thing I know I'd been blasted out into the middle of the intersection.  He never hit the brakes, never even saw me, going probably 35 or 40 miles per hour.
