anyone got a car or ideally a van that runs on this?  after opinions good and bad as thinking of getting a new van sometime in the near future and given the stupid huge amounts of tax on diesel am thinking on getting one that can run on LPG.  any comments would be great!
thanks,

I know a couple of people that have had problems with after market LPG conversions, both on Range Rovers though. I also have a friend that had a pickup imported especially from New Zeland as I believe that over there they have to offer all engines over a certain size with LPG. That way they didnt invalidate the waranty, which I believe you do on most conversions. 

My work has a dual fuel vehicle, cheap fuel no doubt, no difference in performance but more expensive to service and no as easy to get serviced as it has to be specialist. Also I don't think they are very pleasant to fill up, smelly and cold and if you aren't expecting it scary as when you release the nozzel, there is a hiss.
