I don't run a diesel car at the mo, but my next one will have to be as I need a more powerful car for towing the caravan,but don't want a bigger petrol motor as it has to be a work vehicle too.
The cost of fuel and running a vehicle in this country is scandalous, I'm all for another fuel tax protest, if 1 was organised I'd certainly go along and join. They're not finished yet either, its going up again in autumn, by xmas it'll be £12/gallon
