Wanted - a cheap diesel snotter that will return excellent MPG and won't die on me when I commute to work and back.

Change of depot for work means I will be travelling a little bit further each day so instead of busting £80 a week in the big5, I want something that will be cheap to run and can use cooking oil

Cash waiting for the right snotter - must be within 60 miles of Huddersfield and have a heater that works
