Car Valuation Formula & Red Book





Car Valuation Formula lets you calculate True Market Value Of Cars. You will know exactly what the car is really worth, just follow the quick and easy steps…

The most common question asked when buying or selling a vehicle is, what is my car worth? There are many factors that determine this so let’s look at the top 3.

What affects my cars value?

  1. Age and kilometers are the obvious factors.
  2. Car depreciation is usually the biggest factor that affects the re-sale value of any car. As to the amount is usually related to supply and demand of that particular make, model and even color.
  3. Buying habits have changed enormously resulting in smaller cars or city cars becoming more popular than traditional larger family cars. Like the Aussie Falcon or Commodore.

Of course there are other variables to factor in when working out the exact used car valuation like repairs, serviceable parts that need replacing because they’re worn out.

Also if the vehicle has a service history it also helps to tell you the buyer that the seller has put back what they have taken.

You can get this must have information by getting a mobile pre purchase car inspection.

Now usually when you’re buying a used car the seller is usually asking the price he/she owes the lender or finance company. No law against that and not what the car is really worth.

The good news is calculating true market value for a used car is really easy if you follow this simple formula and do your research.
