Hmm interesting thread so I will reply. The steps listed below should get an import complied and on the road: 1) Ensure all modifications are legal and the car is in a roadworthy condition. You may spend lots of money getting car back to 'standard' form, so don't buy an import with too many modifications (especially if they do not have the standard parts that go back on the car). You can always ask the seller to lead you in the right direction to a compliance centre to 'comply' your car. 2) Once complied, get an engineer to provide an engineer's certificate with as many of the modifications that he sees can be engineered, such as aftermarket steering wheel, aftermarket (read WIDE) rims, bucket seats, FMIC not too low and has mesh protection (I think), larger brakes, suspension etc. etc. 3) In NSW, you may need an emissions test depending on what year the motor is (I think?) This can be done at Penith or Waterloo. 4) Blue slip it 5) But your CTP 6) Go to the RTA and get it registered. Bring your engineers certificate, blue slip and paid CTP. Once done, you can have your number plates ! Done ! Your best bet would be to buy something that is ALREADY registered in NSW to save you the headaches. But if you are going to do it yourself, take every necessary precaution because you do not want to be left with a 500hp lemon in your garage that can't be registered.
