Kestrel Take
The Japanese classic that beat the Europeans at their own game — the 240Z's gorgeous long-hood shape, torquey inline-six, and sweet handling made it a legend, and values have climbed steadily. Rust is the enemy (these dissolve), and originality matters. A rust-free, honest, numbers-matching 240Z is a joy to drive and a genuinely appreciating classic; inspect the floors, frame rails, and rockers meticulously (rust is often hidden), and verify originality. A solid body is worth everything here.
