500.00 is chumpchange.. you can part it out and make lots more.. hehe.
I am in same boat though.. wanted the car since new (actually wanted the MKII .. burgandy.. but ended up with the MKIII because of the targa and turbo). Definitely worth the coin in my opinion.
I believe if the alternator or starter wires are not connected properly (tightly and cleanly) this can cause the same issue as well. Also, the ground wire to the body should be attached firmly and cleanly. My 90 wouldnt turn over because the ground wire had actually popped out of the cable going to the battery.
Sometimes, pictures of the car/engine bay help us guess along with you.
