Any options you guys regret or recommend getting?

I'm going with

07 PPW 6SPD Touring
Navigation / Side Air Bags
Splash Guards

am I missing something really worth getting?

 

I just ordered a 07 Grand Touring with airbags, no nav.

I almost ordered a Touring with aeropackage but realized the lil extra for the GT was well worth it in parts.

As far as nav goes, there are at least 6 aftermarket units with MUCH better features than the stock nav and for 2/3 the price.

 

I dont know the stock nav, has a nice clean look, are you talking about the double dins?

plus paying $3500 for brembos and 19s in the back, I dont know, I rather get my own big brake it.

 

If your going to track or auto-x your car, get a base and modify it. You will save money in the long run by not rolling it into your loan (unless you take out more as cash so you can mod it).

Reason being is that you will need better parts then what Nissan or Nismo offers. Nismo will get you about 3/4 of the way there but you will eventually want to swap stuff out.
