1979 Jeep CJ-7 — Should You Buy One?

Kestrel Take

A rugged, simple, endlessly fixable classic 4x4 — the CJ-7 is the vintage Jeep people actually wheel and enjoy, with huge aftermarket and parts support and rising values for clean examples. Rust and hack modifications are the risks (these rust everywhere and get abused off-road). A solid, honest CJ-7 is a fun, appreciating classic you can fix in your driveway; inspect the frame, tub, and floors for rust, and scrutinize any lift/mods for quality.
