    Price or value a car - before you sell or buy!

    Here's a suggestion on pricing your car for a sale (or narrowing down the search when looking for a bargain).
    Red book and Glasses are valuation guide, but maybe you should look at current prices for km travelled to see where you car sits.
    (and this will help you know what you should value your car at for a fast sale in that vehicle category).
    This works for all cars.

    I have taken all the Astra SRis for sale across Australia on carsguide as an example. It's a good sample as it's reasonably large.

    I didn't discriminate between dealer or private sales, only kilometres travelled and price (the two major factors for a car sale).
    Here's the graph:

    As you can see, it peters off quickly from new.
    You want to make sure your car is not too far off this "curve" - otherwise you've under or overpriced your car.

    Here's the values I used (all turbo SRi's too but I didn't graph these as they are a very small sample set):

    Ranked values in order of lowest km to highest.

    Copy and paste these into a .CSV file, open with Excel then add in your value for your car in order.
    You can then make a graph in Excel - too easy!

    Price vs km might be harsh - I know it doesn't take other factors into consideration like aftermarket stuff, driver was smoker/non-smoker, was a careful owner etc, but it may mean you sell your car quicker and know what you can expect to get.
    Consequently you can look at picking up a bargain if its cheap per km on the odo.


    You can also do the same with "Bang vs buck" - price and kW say for new cars.

    I am working on a better formula, km, price and age.
    Feedback welcome.

    good idea... Click here to enlarge

    can you do it as x axis: km by y axis: sale price ?

    just because at the moment, x axis is km and y axis is price/km so the y axis is a component of the x axis...

    hahaha Click here to enlarge sorry Click here to enlarge

    are you able to do it so the price (x axis) is ascending or descending rather than just random prices?

    Ok so you want a sort by price rather than km?
    The line shows value relative to km divided by cost.

    How's that?

    You're welcome - I like this one - it's easier to use to work out your ratio - just divide your asking price by km and see where your value is on this line, or look at your km reading, slide over to the line and then take that value and mutliple by your k's for your expected price - real world market pricing - not a redbook range. It's always better to use publicly-available data.
    Gotta be careful though - what price is listed on the web ad is not necissarily what the vehicle goes for!
