to the forum. The 350z is a fantastic car and I absolutely love mine but I'm not sure I'd recommend it as a first car mainly due to the fact they're RWD and pretty powerful so you could end up in a bad situation if you haven't got a bit of experience.
How old are you exactly? Like Glen said I can imagine if you're 17/18 with 0 years NCB then insurance is going to be massive, I'd guess around £4000+
Plus you've also gotta factor in running cost like tax, fuel, parts etc none of which are cheap.
If you've got the money and you're sure you can handle it then I'm sure you won't be disappointed if you buy one anyways. They're great fun to drive, sound amazing and really look the part in my opinion
