I have a 350Z, a 2005 model, its been a good car, got it when it had 26k on the odometer, now at 65k miles. 4 years ago this summer!
The depreciation is a real b1tch on this car, but as with any thing, they have come down in price.
I use to do a lot of grocery shopping in it, I could drop $200 - $300 worth of groceries and fill up the trunk quite nicely fitting everything in.
I've taken it away for a few weekend road trips out of town, and you can only really put 2 small travel suitcases in it, but it serves its purpose with a little room for some shopping.
As I am older (34) I dont have the lead foot I once had, probably bc I got a stupid speeding ticket last summer doing 10 over the limit. But I guess flooring it away from every stop sign or stop light doesnt do it for me anymore, So I usually drive slower (speed limit) to conserve gas. I typically can avg 350 Miles on a tank of gas....mostly city and some highway miles. When i consistently did highway miles I got around 440miles on a tank of gas.
BTW, since this is a performance car, you must fill it up with premium, other wise the engine will knock on a lower grade gasoline.

www.my350z.com/forumsits a good website, been around since the three fity first came out in '02
damn its been that long, no wonder they are soo cheap
Obviously, insurance is a b1tch as well, and even more so if you are younger. Another thing to consider is costly maintanence, the 30k and 60k services run about $500 each from Nissan.
Overall, its a good car, not the same build quality of my Z32 (300ZX), its very plasticy inside, a little cramped, but great handling, 0-60 is pretty good

, a good, reliable little car
