Have to admit there was a time when I thought the M, AMG and RS had the sleeper credentials down pat. Case in point M5s up to the E39 seemed to hold this with a single M badge on the rear and look not too dissimilar to the mainstream models. Those that came later seem to have to have an M badge on every side.
As for favourites: Volvo V50 T5 AWD as well as the S/V60 Polestar( as long as it's not in Polestar blue), Nissan Stagea and obviously the E39 M5.
