Truly has nothing to do with insurance, which is the case with just about all of the articles we write. (Church and state!) As you might expect, the M cars just establish themselves as collector cars much sooner than ordinary-spec examples. Takes nothing away from the 135i or 128i, which may well have their day in the future as the 318 and 325 E30 are having now, but the standard 1 Series cars are not being treated/handled in the same way the 1M was from the outset.
