11. I say, don't fix the 12-year-old car. My experience:
I spend lots of money on repairs trying to maintain an '86 Corolla. Finally let it go in 2004 with
250,000 miles. It was a good car, but in the last few years I spent too much fixing this and that and the
other. Plus it had become unreliable--broke down on the interstate several times. And in town.
Things were going wrong with it that the average person would never think of. Heard of a harmonic balancer?
The universe had to whack me up side the head before I got it: Replace the car!!!
One reason I waited so long was, I was scared of air bags and what they'd do to me if I were in a wreck.
I'm not any more.
Edited to add: I know, that wasn't your question. I just don't want you to waste any more $ fixing the old car--the way I did.
