Not taken personally at all mate. I have never driven either car in auto form so cannot really comment, I am definitely a manual man even in the new era of super fast auto boxes.
I would agree with your point on traction control if you were talking about the 50 as that was very simple and more of an on/off switch. For me the 70 is heavily advanced compared to the 50 and anyone who has owned both cars will probably agree with this. Also cannot comment on the M as in the test drive I wasnt able to fully utilise the car to traction control needing levels
Funny you should say throttle response, I actually thought the M was sluggish in comparison to the Z but mine has an UpRev so maybe thats why?!
Either way I am still in a massive pickle about my next car so you never know I might come back to the M. Anyway, hope the OP enjoys his new car. Its always fun getting something new to play with espeically when it has over 400bhp!
