M3 F80 chasing Mercedes AMG GTS Nordschleife Nürburgring Touristenfahrten

Lap time 8:21 BTG (cool down last 2 corners and last straight before gantry) Touristenfahrten on an AMG GTS passes me right at the beginning of the track. I am chasing him, he breaks quite early and loses a bit time in bends, on the straight he pulls away (the Sound of the AMG is awesome). Despite me being big in his rear mirror, he didnt want to let me pass until Mutkurve. But i admit, it was fun to stay behind him for a while. The lap time would have been around 8:10 BTG without Problem, b
