On the outside, this 633 CSi is in average condition. The original anthrazitgrau paint is in good condition but shows several defects, mainly due to corrosion. Corrosion is present on the rear trunk, the left rear light, the front fender flares, the right rear fender, the grille tip and the right front jack anchor. A spot of corrosion is also visible next to the left front suspension head. The chrome, plastics and exterior seals are in fairly good condition except for the BMW badges that have been chipped by time.

The interior is in good condition. The original beige leather upholstery looks good despite a rather marked driver seat. The plastics are in good condition without any scratches or cracks. The carpets are stained but not torn. The equipment and the on-board instrumentation are said to function normally.
