Questions/Help on buying a ZR1

[J-Bonez]

I am flying out to look at this 1992 zr1 with 42,000 miles. It has a chip and a tune, and a catback exhaust. "The car was completely stripped down and repainted with all new weatherstripping in 2010. The engine got all new gaskets and hoses and was painted along with the car. The work was done at Vettestorations in Southfield Mi." Everything else should be stock. I owned a 1994 LT1 and when I bought it the Adjustable suspension electronics were disconnected by the ABS computer under the rear compartment. So I plan on checking that. What else should I be looking for to make sure everything is in running order? I have a 600 mile drive home if I purchase this car and want to make sure I am not buying someone else's problems. I've waited my entire life to finally afford this ZR1 and I don't want my Dream Car to blind me of issues it may have. What advice can you ZR1 owners give me on what to test/ look for ? before handing this owner a ton of cash.
