The community's dominant market thesis is that the W210 E55 is underpriced against the E39 M5 and that the gap will close as more buyers discover it. Owners argue it is cheaper to buy and maintain than the M5 while delivering similar real-world speed, and several cite a rapid run-up from roughly $10k not long before.
