Ironically it's not, it's a sodding Enzo underneath!
No it isnt, its somewhere between 300 and 400% stiffer in the chassis for a start. A man at Dallara told me that, he also told me that the stiffest chassis in production was the RR Phantom, by quite a long way.
Anyway, back OT - as brillo said, why not a Z4? Its halfway between a Z33 and an SLK for me, not very hairdressery and the 3.5 goes like absolute buggery. M3's are superb but a fair step up from what youre talking about in running costs, at this point Im required by law to mention that the 135i is a much better car as well
Thanks docwra for putting a Z4 into the mix, great car I agree,
i had thought about one but saw one blazing merrily on the hard shoulder a while back.
I have also seen on you tube a Lamborghini setting fire to itself, wouldn't stop me from owning one if I had the chance though
