Sat Nav was optional, so was GT pack (cruise control, bose stereo, heated leather electric seats). Alezan orange seats/trim was an additional option on top of the GT pack - likewise Frosty Blue was another colour seat/trim which was optional ontop. Rays wheels were also optional, but some late cars came with them.
I thought bluetooth came as standard with the Bose (GT pack) stereo on coupe`s but they didnt fit bluetooth to roadsters.
Parking sensor were an option offered by the dealers themselves, not Nissan.
GT pack was £2k
RAYS were £1k until the MY06 cars
Blue tooth was only introduced on the MY06 cars, previous cars had a cradle that you had to slot your phone into and only worked with phones from around 2001
Sat nav was £1600 or so
Nismo wheels were £2k
Nismo Kit about £2400
Alezan was an option but I can't remember if it was a cost option.
