Question 1: Can you legally sell a car in Perth that isn't registered?

Answer : Yes, you can sell a car in Perth that isn't registered. You don't need a Roadworthy Certificate to sell an unregistered car in Western Australia. You need to give the buyer a bill of sale that has the vehicle's VIN, make, model, year, and date of sale on it. The buyer is in charge of re-registering the vehicle and any inspections that need to be done.

Question 2: How long does it take to sell an unregistered car in Perth on the same day?

Answer: The whole process on the same day takes about 30 minutes:

  1. Give the make, model, year, VIN: and condition of the car when you call for a quote. It should take 2 to 5 minutes.
  2. Booking: Accept the offer and set a time for pickup (same-day slots are available).
  3. Pickup and payment: Usually less than 30 minutes on-site for checking things out, signing paperwork, and paying in cash.

Question 3: What papers do I need to sell a car that isn't registered in Perth?

Answer: You only need three papers to sell a car that isn't registered in Perth:

  1. Proof of ownership: the original or a copy of the registration papers or the bill of sale
  2. Photo ID: A valid driver's license or passport is needed to prove who you are.
  3. Include the names: and addresses of both parties, the VIN, make, model, year, and sale price on the bill of sale.

You also need to pay any fines or fees you owe before the sale and return or remove the number plates to the Department of Transport.

Question 4: Do I need a certificate of roadworthiness to sell a car that isn't registered in Perth?

Answer: No. In Western Australia, you don't need a Roadworthy Certificate to sell an unregistered car, unlike in other Australian states. You can sell it as is without having it checked out. The buyer is completely responsible for passing any mechanical checks and re-registration inspections. This is a big plus when it comes to selling unregistered cars quickly in Perth.

Question 5: What are the dangers of driving an unregistered car in Perth?

Answer: Three big problems with having an unregistered car in Perth:

  1. Council fines: Local councils (City of Perth, Stirling, Wanneroo, and Cockburn) give out big fines for parking unregistered cars on public property. You have to pay to have the cars towed.
  2. Penalties for driving: If you're caught driving, you could get an on-the-spot fine of more than $1,000 and demerit points.
  3. Insurance void: When your registration runs out, your Compulsory Third Party (CTP) insurance is no longer valid, and you will be responsible for paying for any accidents (which could cost you hundreds of thousands of dollars).

Question 6: What is the difference between selling to a private buyer and a cash-for-cars buyer?

Answer:

Factor Private Sale Cash-for-Cars Buyer
Speed 4–8 weeks Same-day or next-day
Cash received 40–60% of value Top market rate based on scrap/parts
Buyer friction Can't test drive (illegal), buyer concerns Buy as-is, no inspection needed
Free removal ❌ Buyer arranges tow (~$100–300) Included
Paperwork burden You handle all transfer documents Service handles everything
Upfront costs None None

Cash-for-cars services will buy any damaged or unregistered car and pay a fair price based on its salvage value, so buyers don't have to worry.

Question 7 : What happens if I sell my car without registering it? Am I still responsible?

Answer : You have to do two things to get rid of your liability after you sell:

  • Return number plates: Take the plates off and send them back to the Department of Transport within seven days. This lets them know that the car is no longer yours.
  • Send in a Notice of Disposal: You must tell the Department of Transport within seven days of the sale who the buyer is and where they live. You can do this online through DoTDirect or by mail.

You won't be responsible for anything after doing these things. The buyer is in charge of re-registering, paying fines, and any accidents that happen on the road.

Question 8 : How do you figure out how much cash to offer for my car?

Answer : There are three things that go into figuring out your cash offer:

  1. Prices on the scrap metal market: Prices for copper, steel, and aluminum in Perth right now (updated every week)
  2. Value of usable parts: How much people want the parts of your car that can be fixed (like the alternator, battery, doors, seats, and electronics)
  3. Vehicle specifications: include the make, model, year, age, and documented condition (engine status, rust, body damage).

The price you see is the price you pay, and there will be no haggling or hidden fees after the inspection. Instead of needing expensive repairs, cash-for-cars services pay based on the car's salvage value and usable parts.
