£195 isn't bad really for that distance. I was working it out the other day and by the time you factor in diesel, something to eat and 2x Dartford crossings, it'd be £100 just in fixed costs. Unless Jarek's conveyance of choice is a lot more economical than my LDV, of course - some of these modern vans are supposed to do daft mpg.
I was horrified at the MPG on that transit I borrowed last week. Just scraped 27 there and 26 back. Perhaps I was dreaming, but I thought - unladen - early/mid 30s should have been easy.
