As for rego costs - in NSW if you go for full normal rego, expect to pay around $1,000 for CTP Green Slip and Rego fees. If your car is "period correct" and you're a member of MOCA, strongly consider going on CRS rego. Allows 60 days unrestricted use per year, plus Club Runs and will cost $96 for CTP Green Slip and Reto. Will also reduce cost of your comprehensive insurance (mine dropped by nearly $300 when I switched over).
