I bought my first and certainly not last G35 about 4 months ago. 2003 sedan 119k. One previous owner. Added plenum spacer, stillen z-tube, throttle body spacer and k&n drop in filter. Wheels are next followed by exhaust upgrade(still researching). That will probably be the extent of upgrades for me in this G. I would like to get a newer manual transmission model to really upgrade! (1-2 years hopefully) Any tips or advice are always welcome. Thank you!

 

Congratulations on your purchase and welcome aboard! Looking forward to see the modifications you have planned!
