Vehicles with the "M Sport" upgrade feature smaller "M" badges on the wheels, front fenders, steering wheel, gearshift and door sills, whilst fully-fledged "M" cars have larger "M" badges on the grille and/or trunk, wheels, steering wheel, gearshift and door sills with the model number (e.g., "M4" or "M5"). Two exceptions are the M Roadster and M Coupe models, both Z3, Z4 and 1 Series variants, which only have an "M" badge with no number displayed on the boot. However, these cars are still proper M cars.
