I looked at 350z's in great depth before deciding to spend less money on a car and more money on other 'hobbies'.
From what I can see now the imports are still a bit cheaper by a few thousand and spec wise they are quite
different. Having a budget of 14k means you can get a nice UK GT one with low-ish miles. I also rather like the Nismo Body kit but the ones I saw with it for sale were also packing nasty alloys and OTT stereo equipment. I am not aware of any major mechanical problems but the newer models have a higher reving engine with produces slightly more BHP at the cost of some torque but are still quicker, the interior has also been revised.
Imho they look much better than a 330ci or a Z4 and I always notice one when they drive past unlike the BMW's which tend to blend in. Whack a Nismo exhaust and they sound 10x better. A lot of people slated the interior but when I sat in one I was really impressed and could find nothing wrong with it and its a nice play to be. They are not up to BMW standards but they are superior to the VX220, Elise and DC5.
MPG wise it won't be anything special expect low 20's around town rising to high20's/low 30's in top gear. Tyres are about £110 a corner and last around 10k miles but it dpends on your driving style and what tyres you get. They also require high octane fuel.
Unfortunatly I did not have a chance to drive one but it does feel like a good quality product and I'd choose one over the other cars any day of the week.
Its difficult to say if its more 'flash' than the others though as different people see different traits as flashy. For example I know people who regards Audis as flash even if said car is a A3 1.6 purely because of the badge. Nismo up a 350z and one person will see it as a loud boy racers car and the other a tastfully modified sports car. I think they look stunning in blue though esp with the nismo kit on though I am not too keen on the rear bumper.
I had pretty much the same budget as you ( still have if I want to sacrifice other things) and I looked at this and thought it was the best all rounder for my needs. I liked the look of the M3 but found them the most expensive car to insure ever and the running costs made me wince a little.
I'd head over to
