Few questions

Hi guys
I'm new to the board and have a few questions regarding the csl...

Ive kept some nice cars in the past and think its time for me to look for a csl if all goes to plan

Firstly the SMG gearbox, Never driven or been in a car with the SMG gearbox, So am curious to how they work?, Ive never seen a csl in person just pics and videos online, All i see is no clutch, a gear stick and some buttons on the steering lol

Secondly i read that they are limited to 155mph. Also can they be de limited?, If so how and what sort of speed can one get out once de limited..

0-60 time, is it safe to say about 4.5secs?

I see a fair few for sale ranging from 25-30k ish minters a bit more.. From a buyers point of view would it be an idea to wait to see if they come down in price? Or should prices stay about what they are right now say for 2009

And where there only 75 s/black models?

TIA
Nick
