I keep the 87 300d 5spd running as long as it's still entertaining to own. It's fun to drive, make noise and a bit of smoke etc but it's in no way a rational decision. There are far cheaper/safer/faster/more comfortable / more efficient cars out there today. A large part of that is the manual transmission. If it was still automatic I would've moved on a long time ago. When I get bored of it I'll dump it. I'm not taking this heap to my grave.
