3 series interior. The exterior is growing on me as not too screwed up like the 6 and 7 series. The same thought creeped into my head this morning about an M3 coupe as one buzzed by (after reading the latest Road and Track comments and thinking about the several track days i do a year), rather than the S5 I have on order but i still think i will enjoy the S5 better purely on design. Hoping i get over the hp loss in the S5.
As tested the M3 did 0-60 in 4.4 and handling is obviously superior to the RS6 so if their transmission works this time and you are good with less room in the back why not.
