I don't know what state you're in but there's generally statuatory warranties. My first preference in this case would be if it has full service history and has valid factory warranty that would be the best way to go for diagnosis and fitment of genuine new parts .
It's interesting to read up on it .
Do you know the vehicle history? PPSR search prior to the deal?
Here's some info copied for QLD, consumer guarantee is also worth noting.
You must give a statutory warranty when you sell used vehicles. Find out what you need to do and which vehicles are exempt.

Statutory warranty period
A 'class A' statutory warranty applies when the vehicle:
- has an odometer reading of less than 160,000km on the day of its sale
and
- has a built date of no more than 10 years before the day of its sale.
The 'class A' warranty expires after 3 months or the first 5,000km, whichever occurs first
Defects
A statutory warranty will cover most defects. The vehicle has a defect if a part:
- does not do what it is supposed to do
- has worn out so much that it no longer works.
A statutory warranty
does not cover defects in:
- tyres or tyre tubes, batteries, fitted airbags or radiator hoses
- lights (other than a warning light or a turn indicator light used as a hazard light)
- an installed radio, tape recorder or CD player
- an aerial, spark plug, wiper rubber, distributor point, oil or oil filter, heater hose, fuel or air filter
- paintwork or upholstery
- air conditioning ('class B' statutory warranties only).
Statutory warranty also
doesn’t cover:
- accidental damage due to the buyer’s own misuse or negligence
- anything the buyer fitted to the vehicle after the time of sale.
Repairs under warranty
A buyer must notify you of a defect. You have 5 business days to decide if you will fix the defect under the warranty. You will need to contact them in writing before the end of the fifth day.
If you
don’t reply in time, you
cannot refuse to fix the defect (regardless of what caused it).
The buyer will have to deliver the vehicle to either:
- your premises
- an authorised repairer of your choice.
You must repair the defect within 14 days, unless you have an acceptable reason.
Excessive distance
The authorised repairer should be less than 20km from your place of business. You can only use a more distant repairer if the buyer agrees to use them.
If the vehicle is more than 200km from your place of business, you may choose to either:
- nominate the qualified repairer nearest to the vehicle's location
- pay delivery costs to use your preferred repairer.
Warranty extensions
You must extend the warranty by 1 day for each day the vehicle is with you for repair or being repaired.
You must record the extension details, including the date:
- the buyer brought the vehicle in
- you returned the vehicle.
New vehicle warranty
You must still give a statutory warranty to the buyer even if the vehicle also includes a new vehicle warranty. However, the buyer can decide to have the manufacturer do repairs if they're required.
Consumer guarantees
A consumer guarantee is a promise that you make to any consumer that buys goods or services. This includes
vehicles and trailers.
Consumer guarantees apply
in addition to any other warranty, including statutory warranty and manufacturer's warranty.
Find out more about consumer guarantees
The consumer guarantees on a vehicle will apply:
- for a reasonable amount of time after the vehicle is sold
- even if the vehicle didn’t come with a statutory warranty
- regardless of any other warranties from the business
- even if other types of warranty have run out.
The amount of time that is reasonable:
- varies from vehicle to vehicle
- will depend on the price and quality of the specific vehicle
- is not defined by when other warranties run out.
What the consumer guarantees promise
You must guarantee that a vehicle you sell:
- is of acceptable quality
- matches any description or demonstration model
- is fit for any purpose that the consumer made known to you before buying (either expressly or by implication) or the purpose for which you said it would be fit for
- is legally available for you to sell
- comes with the right for the buyer to own and use it
- has a clear title
- will have spare parts and repairs available for a reasonable time
- will live up to any other promise that you make about its quality, condition, performance or characteristics.
You
cannot refuse to honour a consumer guarantee. Nor can the buyer sign them away.
Consumer guarantees
will not cover:
- accidental damage due to the buyer’s misuse or negligence
- anything the buyer fitted to the vehicle after the sale.
How they work
A buyer can seek a
remedy if a vehicle
doesn’t meet a consumer guarantee.
Find out more about
remedies and refunds.
Under consumer guarantees, a failure may be corrected by:
- returning the vehicle for a refund or a replacement
- getting repairs to the vehicle
- compensating the consumer, such as for a drop in value.
