I have to disagree mate, I dont think the c4 is a fast car, yes its quick like a 350 or 370 but to say its scary quick seems very odd to me. The 911 is more focussed then a 350/370 and the power delivery and handling is something you have to learn, the car is older and the seating position is lower so you feel the speed more than in a modern car. In the same way a 350/370 is quick but deceivingly quick, you dont realise how fast you are going until you look at the speedo
I had my c4 for nearly 4 yrs and at the same time my brothers both had c2's, pretty much the same cars until you push hard, steering is a little heavier on the c4 and you definitely feel the front end light in a c2 more
they are now gone replaced by a rs focus, 370z and a 911 turbo, the turbo is a fast car as is riding a bike is fast but I really dont see the c4 as fast
Not trying to diss you're opinion but it may well mislead people
Unless you have driven both its very difficult to explain the difference in the power delivery as you will now know, they are great cars otherwise I wouldn't have kept mine for so long
I agree with ekona get yourself to Cog, Chris is a genius, he doesnt use generic figures he will make the car handle they that suits you
The handling on the 911 is the most sensitive I have ever known on a car, even new tyres can totally transform it and worn do the opposite, many people think the have problems only to find out the tyres need changing ( not just worn but out of date, flat spots due to standing etc)
