Bill,
I found my Z11 in 1994, about 140 miles from my house in West TN. I looked at the car pretty carefully - determined that it was what I had been searching for for a lot of years (and numerous dead ends), and bought it. Trusting my own inspection, and with my extremely pregnant wife and two young children following in the family Suburban, drove the car home. Good thing the car is an air car - 10 minutes after I left the guy's shop, I ran into an frog-strangling monsoon rainstorm. Defroster works really good on an air car - and a good time in the rain to find out if your top leaks !
Wild ride on bias ply tires at speed (3.08 rear, 350 THM), but it was an enjoyable one. My point - if it's a driver, drive it. Make sure your cooling system is up to snuff, fluids are good, tires inflated and good tread, brakes are up to it, and have a chase vehicle in case. Should be good to go -
Regards,
Steve
