look man i got my red P's 6 months ago, and i got an exemption to dirve my skyline, and that skyline only. i am not entitiled to drive any other turbo car, so even if i sell my current skyline and buy another i wnt be allowed to drive the new 1. so there are small exceptions that may allow u to drive a turbo car. 1-owning the car b4 the rule came out 2-needed for work purposes 3-any other valid reason u may present to them.
but to drive a turbo skyline on ur P's is like handing the police ur license. the fine on the first offence is around $350 and 7 POINTS. thats first ofence. so realisticaly speaking either apply for an exemption (if u think you have a valid reason). otherwise simply dnt take the risk, unless u feel like losing ur license for 3months everytime u get pulled over randomly(which is pretty often in a skyline lol)
