This site leaves me very confused sometimes. The constant theme from many (sensible) posters is if you do only low annual mileage don't buy a modern diesel, a view I subscribe to. Yet on this thread the advice appears to be buy the diesel, it will save you money not only on fuel but also on deprciation.
Whilst I accept that the diesel will be worth more at 3 years I doubt it will recoup the £2000 purchase price difference. But even if it performed vastly better over 3 years any advantage could be lost with costly DPF issues.
So whilst past performasnce is no gaurantee of will happen in the future I have investigated used values of 3 years old Superb petrol and diesel models. Back then the petrol was the 125 PS model and the diesel was the 140 PS and to do a direct comparison I have had to use the S trim for both (no petrol 1.4 SE).
So in March 2014 a Superb diesel woul have cost £1800 more than the identical trim 1.4 TSi. With 30,000 miles the diesel is now worth £1450 more as a PX.
Thus in pure depreciation terms the 1.4 TSi would ahve save the owner £350 but that would have probably have been spent in extra fuel over those miles.
So based on that over 3 years for a private owner its pretty much identical.
Guess its down to personal preference and acceptance of the DPF risk over low annual milages.
Might be different for bussiness leasing customers but having done some investigations its nothing like the difference quoted above.
Using the same company, some mileage (10,000 pa), same deposit the diesel was £210 pm whereas the petrol was £224 pm. But from the users viewpoint the petrol is cheaper. BIK for a basic rate taxpayer is £74 for the petrol and £81 for the diesel.
Personally I think its an honorable draw.
