Go for it! I'm 21 earning a bit less than u and I bought my z 3 weeks ago. My last car was a fiesta st 2.0 so not that different to a c2 vts. The 350z is so much more car in every way looks, performance, spec, ect. The only thing I didn't budget was 20mpg on super unleaded but still worth every penny if u love ur cars as I do.
