That is still a good price!
Yeah, you can drive to the workshop on your tyres, but you must have a new/current receipt for them, else they will not comply. There are a heap of different things you have to do before the car can go in for compliance .... you have to sign a RAW work agreement form and pay $1,265 deposit before they can even apply for an import approval. An approval takes between 7-10 days and comes from Canberra. Only then can they even think about actually doing the compliance. It is vital you/he get a strict inspection somewhere else to make sure the car is 100% ok for compliance, as if the compliance workshop finds one tiny bit of dent or rust in the chassis or vital parts, they will immediately and without discussion brand the car damaged, and you can NEVER get it complied in Australia - even if you fix the damage. The car then has to be scrapped, or you have to pay to have it exported. They take this VERY seriously, and there is absolutly no leeway for compliance workshps, they 100% work within the guidelines.
