Jez/Andrew,
Agreed - I think it's a Lexus sc430 front with a Hyundai arse-end. Initially I thought - hey, this looks good; but after a full exploration of this site, it got the thumbs down.
Clear influence here - the question is, will people say "Oh, that's a rip off of a 350z" or will they say "It's a rip off of an Audi TT!!" <img src="http://www.zclub.net/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt='
