It's gone up again?! I actually dread to think what each mile has cost in my Zed in the last year. Factor in depreciation from the forecourt, fuel costs, tax for the year, insurance and the ridiculously low amount of miles I do and it's staggering. Still I do love it which is why I'm going to take it out now since it's a nice summer night.
Husky reckons with fuel his Zed has cost him (including all the stuff you mentioned) around 20k in 2 years.
