16-valve DOHC engines arrive in the UK and the Turbo 16 and later Turbo 16S become the performance cars to have, alongside the 900i 16 and a more refined cabin.

Popping out of reverse, Whining in 5th gear, Difficult shifts
Structural rust in the wheel arches and floor can be terminal if not caught early.
Visible bubbling, Soft metal in the boot floor, MOT failure on structural points
