Kestrel Take

The original pony car — the '65 Mustang launched a legend, and early cars (especially the '64½, GT, and fastback) are highly sought. Like the '66, it has bottomless parts support, a huge community, and simple mechanicals. Rust and originality are the whole story. A rust-free, honest '65 Mustang is a wonderful, easy-to-own classic and a rock-solid buy; inspect the floors, torque boxes, and shock towers, and verify the body and any GT/fastback/K-code claims. Solid body beats everything.
