8500 for 150k mile 90 Z TT? A bit much and say no thanx!
It's ragged on man...that's why it didnt go. Those Z's are quick and if it didnt feel quick it's b/c it's out of tune, turbos are about ready to go or engine is busted up.
I'd pass and wait for a lower mileage one w/a decent price.
DONT GET IT!
