Do I need a roadworthy certificate if the car is still under warranty?

Answered by David Morley · 28 Aug 2020

These rules and regulations vary from State to State, but the bottom line in Victoria is that, yes, you do need to provide a roadworthy when selling the car privately. Aside from a very small trailer and a range of road-going commercial and industrial equipment, the only vehicle in Victoria that doesn’t need a roadworthy certificate (RWC) as part of the change to new ownership is a brand-new vehicle. The definition of that is a vehicle that has never been registered in Australia before and has covered only kilometres involved in its sale and delivery to its first owner.

The factory warranty has nothing to do with RWC law as different makes and models have differing warranty periods. If you want to sell the vehicle privately without a roadworthy, you need to remove the number plates and hand them in to VicRoads on completion of the sale. The exception to that is if you sell the car to a licensed motor car trader, as the responsibility of gaining a RWC then falls to that business.

BMW 4 Series 2019: How do you press the front seat forward?

Answered by Graham Smith · 12 Jul 2019

Press the seat position button on the shoulder of the front seat to move it forward, and then fold the seat back forward and you should have easy access to the rear seat. You should also check the car’s owner’s manual.
