I have an '88 Jetta with approximately 125K miles. It looks like hell. Serious body damage (but no rust). Faded paint. Back seat has a nasty rip. Nonetheless, it is perfectly drivable. It has been in roughly the same condition for the last three years and I'm still driving it. At this writing, I have yet to collect the "new" car from the dealer.
So what should I do with the old car? By standard metrics it doesn't really have any value yet it is a functional vehicle that passes smog. Is there any hope of preventing an awful waste?
