I'm new to this forum, i just found this site tonight and it makes me even more excited to possibly a z owner. i found a 92 300ZX with 117K mi on it. the timing belt(which i read is one of the few achilles tendons of the z32), radiator, and clutch has beeen replaced. the heater core needs replacing, along with the shocks. im considering KYB and koni shocks(both adjustable)...good choices for this car? Also how hard would it be if i wanted to replace the heater core myself, whats included in it? and last, what should i look out for when i go test drive this car next week? good buy or should i keep dreming and looking?
