Is there any Motor Expenses s/w out there?

Having just got my hands on a P900, I want to use it to keep track of all my motor expenses, fuel, mileage, MPG, services etc. etc. on my 3 cars.

I used to have a fantastic bit of s/w on my old Psion 5MX that did exactly what I wanted it to do, but alas the guy stoped developing it when Psion announced that they were pulling out of the cumsumer market. 😞

So, back to the question...

Is there a UK biased piece of s/w that will do what I need? It must work in sterling with litres as the units with a conversion to MPG at the end. nI've looked at AutoLog but its US based.

Any advise/links, much appreciated.
