I would say that if I were to put the two side by side and gun them, the scoob would wet all over the M3 up to around 100. After that, the M3 would steadily reign it in.

The scooby feels electric, really punchy, always wanting to be pushed. It sounds funny, but the scooby is just not easy to drive slowly. It always feels like it wants you to drive it hard.

The M3 is definately more refined and extremely easy to drive at slow and fast speeds. The torque in the M3 is brilliant, it always feels like it wants to pull and keep pulling hard. It only lacks that turbo punch that the scooby gives you.

With regard the "Ring" I would imagine that there would be very little difference between the two time wise. The scoob would be much better in the twistier sections and would get out of the corners a lot quicker. But the M3 would pull it all back on the longer sections as it would be wound up already.

In essence. I am extremely lucky to have both and appreciate both cars as they are both magnificent in there own rights. The scooby still puts the biggest smile on my face though
