I'm looking at a '72 240z, one owner, 173,000 miles (engine rebuild at 90,000). The interior and floor is excellent, paint is fair (silver). Rust on top of right fender (starting to bubble), Rust around rear wheel wells and the rear corners of the rocker panels are rusting through. Dual carb set-up, no tranny work ever done. Is $1700 a fair price? Any info. or opinions greatly appreciated. thanks.
