Just ordered the M3 AWD and I’m looking to get a charger for my home. Only issue is, my car is parked at the end of the drive, which is 20m away. I really don’t want to rip up all the slabs (only been down a year) and put a column up at the bottom of the drive. So my only option is either a charging cable 20m long or an adaptor. Anyone came up against this before? And if so what did you do?
