It is not an easy decision to make. The main consideration is plonking good money into a depreciating asset.
Let's do the sums for a Honda Fit to be scrapped.
(Installment + usage/maintenance) per month = $1,083. This sum includes petrol, parking at home & work, ERP, insurance, road tax and regular servicing, changing of parts.
PARF rebate at scrap = $9,500.
So, after scrapping the car in December I get an 'increment' of $1,083 per month and a $9,500 bonus?
OK, take my car.
