Just a quick update from a personal experience on driving barbz's 'green hornet' beast; while mine is in for an update.
It is the most brutal car I have personally driven. My cousins are well off to be polite, so I have driven Maserati's, all manner of Porsches and a fair few fast boy racers (inc. Nissan GTI-R, Elise etc). However the 'green hornet beast' (my term for it) accelerates like a phenom and goes like a rollercoaster.
Just when you think you have a fast coop, try this and your heart resides in your throat, and the adrenaline flows like a river.
and yes I feel like a pedestrian in my coop now..so my coop demands MORE POWER!!
