1988 Chevrolet K5 Blazer — Should You Buy One?

Typical asking price: $12,000–$32,000. There is 1 high-severity known issue you need to know before handing over a check.

Kestrel Take

The full-size, removable-top Blazer is a squarebody-era icon riding the same hot classic-truck wave — clean 4x4s with the small-block V8 keep climbing in value. Rust (especially where the removable top meets the body) and crude modifications are the risks. A solid, honest K5 is a fun, appreciating classic you can wheel and fix yourself. Buy the rust-free one and enjoy the top-off life.
