The F20 M135i launched in 2012, going against the grain of every other "hot-hatch" manufacturer, utilizing a RWD platform, and shoe-horning the N55 3.0 straight 6 turbocharged motor up front.
Little did we know, BMW went on to use the N55 platform for the original M2, which means that the F20 M135i has a plethora of aftermarket options, and a fanbase to boot.
