Buying a car is exciting, but it is also a big decision. It’s not unusual to sign the paperwork and have doubts if you’ve made the right decision. In South Australia, if you’ve bought a used car from a licensed dealer, you’re protected by what’s called ‘Cooling-off Rights’. These give you time to think things through before you’re fully locked into the contract. 

Cooling off period for used cars

Here’s a simple guide to how it works, plus how Cars24 makes sure you’re covered with extra car buying freedoms.

What is the cooling-off period?

When you buy a used car, or even a demo car, from a dealer in SA, you have two clear business days to change your mind. Saturdays also count as business days in these parts.

During this time:

  • The car stays with the dealer.
  • If you’ve traded in your old car, it stays with you until the cooling-off window closes.

At Cars24, we go one step further. Every buyer receives a 7-day return policy, so if the car doesn’t feel right, you can return it for a refund.

How do you use your cooling-off rights?

The cooling-off clause isn’t triggered automatically; you must notify the dealer in writing before the short window of time expires.

You can do this the following ways:

  • In person at the dealership
  • By registered post
  • By email or fax
  • Or by handing it to a responsible person at the dealership

Always keep a copy of the notice for your records.

What about deposits?

Dealers can ask for a deposit of up to 10% of the contract price. If you change your mind during the cooling-off period:

  • The dealer can only keep 2% of the contract price or $100 (whichever is less).
  • The rest must be refunded by the next clear business day.

Can you waive your rights?

Yes, you can sign a waiver form if you want to take the car right away. But:

  • The waiver must be signed in front of a witness who isn’t part of the sale.
  • Dealers are not allowed to pressure you into signing.

We always recommend using the cooling-off time. At Cars24, you’ll also have peace of mind knowing every car has passed a 300-point inspection and comes with a 3-month warranty.

When cooling-off doesn’t apply

Cooling-off rights don’t apply if the vehicle is:

  • Brand new
  • Bought at an auction
  • Bought from a private seller
  • Bought by another licensed dealer

Final advice

The cooling-off period is a valuable safeguard for South Australian buyers. It gives you space to rethink, review the paperwork, or double-check your budget.

And with Cars24, you’re protected even further, with a 7-day return window, thorough inspections, warranties, and home delivery. We want you to drive away happy and confident in your decision.
