Take one for a long drive on a variety of roads, before make your decision. I was left feeling its an over hyper car to be honest.
I drove a 55 reg model, on a fast smooth A road I know well and thought it was good, went on to a bumpy b road (I know very well and travel down most days) and it didnt feel that quick or good at all, back end did not have enough grip and could not get the power down due to its lackof rear suspension travel - could not keep up with my 7 month pregnant sister driving my Subaru Impreza (running approx 280 bhp) ! On a damp road it was terrible, didnt think much to the brakes to be honest either.
