This E46 is finished in distinctive Laguna Seca Blue paint and features M3-specific bodywork including unique bumper covers, side skirts, mirrors, front fender grilles, a rear valence, and a power dome hood.

The CARFAX report shows minor damage to the left side in July 2024 and the seller states the driver’s side door and rear quarter panel were refinished as a result. Some stone chips and scratches are noted on the front end as well as a ding on the passenger door, a blemish on the trunk lid, and some fading on the passenger-side mirror housing and roof. The rear tires are also said to rub occasionally. Detailed images are provided in the gallery.
