For what it is worth, I bought a 2002 M3 6 mt last year from California. It was a sunroof delete car. Body in great shape. Brought it to Canada and did all legal work. Just did it to see what an M3 was like. I went to sell it this year for as little as $15500. It was the cheapest M3 listed in ALL OF CANADA. Had NO calls or emails. Many looking at the ad but no responses. Canada prices are generally higher. Add a salvage title to that and you will almost have the $9500 2001 M3 convertible I walked away from in Las Vegas.
Enjoy the car but do not plan on any profit from it. My daughter sure enjoys mine.
