I got in on this thread late, but here goes, I restored a 1984 Z51, it was a freebee, ran ok, but everything else was worn out, it was an interesting project, learned how to fix the digital dash myself, balanced the throttle bodies, which I considered an easy job, a little time reading the FSM goes a long way. After all the work, driveline, digital dash fix, interior restoration, new exhaust and just about every other system on the car was restored or replaced, I sold it to a very happy person for $5,000, which was by a weird twist of fate the sum total of the parts I had bought new and used to redo the car. Was it fun, yes most of the time, did I get a tatse for another Corvette, yes!! I am now the proud owner of a really nice 1996 coupe, so I have had the 1st and the last C4! Both are and were a joy to own.
