Future Plans

Currently, the car is as close to being "done" as it ever has been; there's literally not much else I can do to it...pretty much everything has been modified for the better. The older I get, the more pragmatic I become, and so with neither a job paying a handsome salary, nor the need for any more changes, my 240sx may, for the first time, stay unmodified for the next few years.

Nonetheless, I still have a few things I'd like to upgrade: 

-Wilwood 4-piston billet calipers and 2-piece machined rotors for the front ($795) 

-Side-skirts/rear-valence (body/appearance items are always the least important to me)
