who's got there x5 converted to lpg? i have a e53 3.0l petrol and the mrs is always complaining it costs two much to run and we should part x it (no chance!) and get something more fuel efficient. at the moment we put in betwee £40 and £60 a week so i want to get it converted to lpg, anyone had it done? what system should you go for? what did it cost and is it worth it?

cheers jon
