You see there was an estoril blue e46 for sale on usedcarsni with 20k miles? Looks nice.
@scotty733 is selling his Evo VIII I believe if you are open to something like that also. Looks a mint example.
e46 sold? Jeepers lol
There was a red evo 9 which looked good on paper on MLR.. no pics or anything so may still be about.

Didn't read the full ad, new engine, I'd say that would put you off lol
Just sold my M3 there recently, silver might not be to everyone taste, but it's hard to argue with the history and brand new Vanos from Country Garage with warranty, as well as a non cracked subframe.
There are some amount of doses out there now!
