What the data shows

This 1998 Z3 2.8L manual with matching hardtop is a solid weekend car. Key needs: cooling system refresh ($800–1,200) and immediate tire replacement ($500). The clean, rust-free body and desirable options make the $9,800 price reasonable, but the ignition cylinder and airbag light should be addressed promptly.
