Before you buy a car, it's a good idea to do a rego check. You can check a vehicle's registration details online for free through Service NSW. All you need is the vehicle's NSW registration plate number to find:
the registration expiry date
whether the registration is suspended or cancelled
any registration restrictions
any registration concessions (additional charges that might apply when transferred to a new owner)
the Compulsory Third Party insurer and policy expiry date.
