Thanks Patrolman, might try my local - my challenge is order - I am currently without car, ideally it would be buy car 1st - find source of VWO - then buy bio diesel processor, ideally this means I can get a Terrano, but if I cannot go the Bio route I really need to be looking for something that does circa 40mpg, which rules out pretty much any decent 4x4. Am hoping maybe an R3MR will be good on fuel, for a 4x4 at least....
