Just a quick word on resale values. I'm 40 years old and I've seen so many years and models of cars go from being everywhere and worth nothing, to rare, hard to find and worth half decent money in 10 years its scary.
As long as people keep hacking them to bits, sending them to the crushers and parting them out, the numbers of them keep dwindling until they're all of a sudden hard to find. THEN they'll be worth a lot more than they are now.
The Mk2 Supra is already climbing in value here in Australia, Mk3's will surely follow.
So stop junking perfectly good cars, if you don't want it, sell it on to someone who does.
So, to say it's not worth fixing, well, maybe not now, but give it 5-10 years and that not worth fixing car sill most definitely be worth fixing.
