For Matthias Unger, the season when the leaves of the forests change from a rich yellow to a bright red has a very special charm. He utilises the last rays of the sun by grabbing his amazingly simple M logo-bearing ignition key and heads to his garage. Awaiting him here is a very special automobile. Matthias Unger's BMW M3 Sport Evolution from 1990 is to this day an irreplaceable piece of motorsport history with road approval. We accompanied him on a drive and were able to experience what it means to take to the road with an almost three-decades-old sports car.
