I don't really understand what you lot mean by heavy clutch but then I've had so many cars I just get used to driving whatever I've got but certainly don't find it a problem and I sit in lots of traffic on my way to work.
I saw a skyline 350 at Trax this year, is this a different car to the one you guys are talking about? Was just like a Z but with back seats, same engine etc according to the guy who owned it. It's in this link fifth car down.
