I recently got a 2006 G35 White 9800 miles 6spd Black and slate interior. I paid 29000 for it is that a good deal? The only thing it dosnt have is nav.
Also what can i do to make it faster without spending alot of money? I put a HKS intake on it and I was thinkin about a borla exhaust headers back. Should I or shouldt I.

get a MD 5/16 spacer and exhaust + testpipes/HFCs

The only mods worth mentioning is forced induction. Every other mods (intakes, exhausts, header, etc etc.) will increase performance but you probably won't even "feel" the difference from stock. Those mods will cost over 2grand combined. And it won't even shed off a second off the 1/4.

Those mods are mainly for looks and sound.

If you plan to go forced induction, it will cost $$$$. But remember this rules. Of the the 3 you can only pick 2.

* Fast
* Cheap
* Reliable

1) Fast & Cheap = Not reliable
2) Cheap and Reliable = Won't be fast
3) Fast and Reliable = Won't be cheap

put some stickers on ur car

each sticker = 5WHP =D

^^ lol it's the same with girls without the fast part.. =]

x2

and maybe a tune as well. . .
