Just bought a $500 z24 convertible thats been sitting in a garage for 8 years. 128k miles.
first step was to clean the heck out of it. Mold mildew and an inch of dust just to see what i had gotten myself into.
second step ive changed oil, oil filter, spark plugs, boots, trans filter, fluid, gasket, fuel filter, coolant, serpentine belt, and pulley.
still haven't started it yet. Don't want to start till i have time to diagnose/ fix issues that may come up but my next plans and parts are all new brakes tires.
any common issues i should be looking for? Any suggestions? Pictures attached are from day i bought it.

 

Welcome from Florida. Make sure you drain the gas tank, clean the gas tank and fuel lines.

 

hey from maryland. Yea i pumped out the tank. Lines arent dryrot and i replaced fuel filter. Lines look in good shape. I shouldnt have to replace them should I? Its such a small amount that might be in the lines. I feel like it should be fine.

Ive got the alternator and condensor and ac compressor pulled off now. Both alternator and compressor pulleys are rusted up and siezed

 

Great score!
The valve train, cylinders, and other stuff are probably completely dry. Removing the plugs and valve cover and shooting oil all over everything will reduce wear on start-up. If you can't do that, Crank the engine with the fuel shut off or the plugs removed to get the oil circulating.
My 02 still has all the original rubber hoses.

 

If you do crank with the plugs out, better ground the plugs, just in case.
