Screw the wagon concept. What we need is an AMC Pacer-styled M3. Way better lines than any wagon and full of win.
All kidding aside, anyway who thinks that BMW should make an M3 wagon should be dragged out and shot. Why on earth would you request the bastardization of the beautiful lines of the coupe and sedan by sticking an ugly ass bubble on the back. May you all burn in the firey pits of hell for such blasphemy.
