this is my 09 black ed. sadly no bose audio, no keyless entry.
I thought keyless entry was standard and didn't double check before I bought it, silly mistake.
My tyres were manufactured in 09 as well, with 20k+ km is it due for replacement yet ? if so what options are there besides re070 ?
I am also considering an exhaust mod. I have Akrapovic on my other car and I'm considering doing the same for the GTR.
but i think the Password exhaust sounds nicer.
Where do u guys service your car ? ATS ? i have a tyre pressure light on currently.
also does the tyres need to be inflated with nitrogen ? or can i mix oxygen ?
sorry for the newbie questions.
