My Brother in Law's 93 which I often care for mechanically has over 345,000 on it. I'll have to check it soon - he was here in it Friday and I see it weekly. Will let you know. Original drivetrain and - get this - original windshield!
All original gaskets, and all under the hood the only thing i do is keep up with the air filter, clean gas like "gum out" every 200 miles and little maintenance oil changes i do on my own.
Common Sense if its taken care of it will run forever in the next 3-4 months i might hit that million
