I have a background in cost benefit analysis so am a complete anorak on the subject of how expensive it is to run my car. Works out as:
15p/mile fuel
29-ishp/mile repairs, servicing, parts, labour. This is the first killer. What a lemon.
22-ishp/mile depreciation (other killer, this is why I put a range in, should get definite figure in next fortnight because I want to see back of it forever).
VED (tax), MOT, insurance are all EXTRA. Those are fixed costs. It costs about £550/yr just to have my car sitting on the drive ready to go. Car costs that much even if it never goes anywhere.
Our previous car probably cost half as much to run, but fuel was cheaper 3 yrs ago, too.
it seems to me like people who need to fill up 2-3x/week aren't really going to refuel any more often than usual, are they? How would they have time for that, on top of all the driving they need to be doing (for work, etc.)? I think the panic buyers are most likely to be the folk who usually refuel 1-2x/fortnight. I would love to collect stats & analyse the social character profiles of panic buyers, too.
