Just wondering peoples thoughts, obviously the cheaper road tax for diesels on the new emissions scheme is a bonus for cheaper tax, but in general, how many miles per year warrant the purchase of a diesel car?
I'm currently doing around 12k per year on 2L petrol (road tax ~700).
12k miles or kilometers? Neither really justify a diesel as the purchase price is generally higher. What's your budget and what kind of car are you looking for?
Pre-2008 as a general rule diesel would pay for the higher initial purchase cost after 100k miles.
Since the new CO2 based system came in in 2008 I don't think it's possible to generalise.
12,000 miles. Budget around 15k, like the Accord 2.2 CDTI. The new 09 shape is fantastic looking, but a 08 on the new emissions scheme would be good.
I made this site to help answer this question from a pure fuel running cost perspective (ie not tax or initial cost etc):
Its not cleaned up and pretty yet but the calculator should be sound.
Choose either L/100km Euro (metric mileage and Euro Cents) or UK MPG (and put in the number values as if they were Euro cents ignoring the £ sign).
US MPG obviously not applicable here.
Great site, nice to see all the details. Is there a way you can work in the road tax as well? If you don't mind I'd like to link to that site for a future article?
I could add in further calculations for Road tax, but Im unsure on how to approch it.
It could make it look very complicated, consider 10 tax bands before 2008 and 7 afterwards, on both cars you want to compare, plus all the fuel calculations.
I guess I could add a column where the user inserts Tax (annual) but leave it default at 0 for all, therefore those that dont understand it wont be affected by rogue calculations.
You can indeed link to it, though I really need to get it looking right!
Great site, give a clear understanding of the advantages and disadvantages. Very useful.
God be with the days when we changed our cars simply because we had a desire to own something new(er)
Modern life unfortunately.
