Drive the camaro. Just kidding, I have an 84 camaro too.
seriously though, it appears that you have your hands full with the work on a vehical that has served its purpose.
there comes that time you know.
You are already in need of head replacement and altenrator, you havent done a capacity/load test on the battery, that could be dead from not being fully charged and might come back to life.
Lost of miles on there to be sticking a few hundred now, and what is next.
I dont know how good the body and undercarige is but there are other issues that come at that many miles as well.
If your going to do the work yourself youll save a buck or two there but to save a dollar and buy something newer with less miles might be an option.
As much as it sucks right now, the economy is forceing people to sell cheep so local smaller town papers and even the auto trader has some awfully tempting prices.
