Nice write up, good comparo. The lower limits of older cars is what I was missing for years. I used to love driving my 2002tii through our local canyons easily 4 wheel drifting out of the corners at a speed that was much more Safe? than what can be done in a modern high performance car, including the 1M. While the 1M will kick out the rear end very easy, it's still takes a huge amount of speed to 4 wheel drift the car.
Cars like the GT3 4.0 and greater are unusable around town other than the drive to Cars and Coffee and or the race track that most will never see. Fabulous collectors car though
