Hi mate, I'm an owner of an '08 plate since new. Basically the main points are:
Coupe or convertible, only two trim levels available to uk; base and GT. GT gets cruise, leather heated seats, and a rubbish BOSE stereo.
2002-early 2003 Jap import only.
2003-2005 original UK 276bhp model.
2005 GT4 model, as above but with uprated 296bhp engine.
2006-2007 296bhp engine still, but with updated interior, LED rear lights, and RAYS alloys as standard (previously optional)
2007-2009 80% new 309bhp engine and a "humped" bonnet.
£440 tax for post march 06 models, Insurance not bad, i pay £400 fully comp at 29 with 4 years no claims.
23 – 26mpg generally. 28 – 30 on a long run.
Only a few common niggling issues, clicking rear axle, skipping Bose CD player.
Engine generally bombproof, no cam belt either. Brilliant drive, meaty controls and an indulgent chassis. I love mine to bits.
350Z-UK.COM Owners club, of which i'm a member. Very friendly, totally free, and a huge source of info.
And yes, it's rubbish for bikes! 🙂
