NSW used car: what dealer paperwork and disclosures should I keep?

Keep every document the dealer gives you: the sale contract, prescribed dealer notices, any finance/cooling-off notice, warranty or dealer-guarantee material, inspection or repair records, and written representations about the vehicle. NSW motor dealers use prescribed forms for disclosures and dealer-linked finance. If there is later a dispute, those documents can be important evidence.
