Daily drive is a 4.0l XK8 (X100). I'll do at least 1 tank a week (£70ish) just going to work/general bimbling. I'm averaging 23.4mpg so that's around £3700 a year.
If I'm out at the weekend that can easily add another tank of fuel.
That'll be why I'm always skint but what the hell.
I've done 9100 miles since November in the Aygo and fuel spend so far is £933.
Conversely, I've done 7560 miles in my 180SX since September last year and that has cost £1580. So you know. That's been of the road for 8 weeks now though with a buggered gearbox / turbo / electrics.
Around £220 a month for the M135i. Average is about 23mpg at the moment, I could get 34mpg driving like a saint but would be bored senseless and then still think I'd get 50mpg if i had a diesel.
