I agree with Ilya too -- loved my M45, and I really enjoy my M37.
Depends on what you want to drive: smaller, more sporty, but less luxo - Q50
more room, much nicer interior, but still sporty - Q70
there is a thread on the M37/56/Q70 forums where members debate Q50 vs Q70
might be tempted to trade for a Q50 Red Sport, though (twin turbo, 400 hp)!!!
