Hi there, I bought a d2 51 plate 3.9v8 es 4 weeks ago, 64000 miles with all mots for £1700, it is in mint condition. I bought it for a family trip to Cornwall which it did without a problem. We covered over 1000 miles whils away. its sat on the drive until last weekend when i went to Eastnor Castle lr show at the weekend, a 400 ish mile round trip, it never missed a beat. Its not on lpg and i dont intent it to be either, it a family weekend/camping vehicle, I reckon im getting 17-18 mpg. i have a few other vehicles including a 200tdi defender. I dont think it does much less mpg than fender, although thets only used for laning.If your happy with it (and lets face it a v8 will always put a smile on your face) then it doesnt really matter what it cost to buy or run
