  • FS: 1991 Diamantschwartz 2.5 (SoCal)

    1991 BMW M3, very late 11/90 production car, Oils & Fluids from the end of production for E30 M3. 146k miles on chassis, approx. ~45k miles on Mario Langsten-buit 2.5. Most of the mods were done either by Don Fields (Mr. M-Car) or Mario Langsten (Vintage Sports & Racing) or Mike Morris (Schneller) – E30 M3 luminaries. This build is impossible to replicate for this price (asking $70k).
    I've owned the car for the last 20 years. Bought it circa 2002/2003 in Boston and relocated to LA about 6 years ago. I believe I'm the 3rd owner. Car has always been garaged while under my ownership. This car has been my pride and joy but the upcoming move overseas (where I won't be able to enjoy it the way it's meant to be enjoyed) forces this sale. It was my dream car growing up and I bought it as soon as I could afford it (back then there was a "$15k rule".... well, I bought it for $17k back then).

    Diamantschwarz with black interior. Car is set up for track\canyons. It's a BLAST to drive but not the most comfy car - no AC, no sound system, race seats, no stock seatbelts, no rear seat. Recent (Nov’ 22) respray in original color, recent oil\tranny\diff oil changes. I’ve been using Motul 300v motor oil and Redline fluids in diff\tranny. Car is due for a coolant and brake fluid change this year. RMS is leaking a bit. Mario tried fixing it years ago but the fix only lasted a couple of weeks :(

    I’m sure I’m forgetting something....Asking $70k. Serious inquiries only. Not in a rush to sell it, want to see it go to a good home. Car is currently not posted anywhere else… wanted to give my S14 family (even though I’ve never been super-active on the forum) first dibs. Car is located in Calabasas, CA
