are they more expensive than the equivalent petrol to insure, i've never owned a DERV, despite being a diesel engine test engineer

been looking at 5 series and did 2 quotes back to back and the 530i was ovber £100 cheaper to insure than the 530d

got about £4-5k to spend on a new 5 door daily...ideally would like a diesel as the economy on my FRS was shocking so would be nice to have something that does mroe than 250 miles on a tank full
