I passed a garage selling LPG in Barnsley today. It's hardly the priciest place in the world, but it was 65p. Has it gone up that much? 
They must have seen you coming. 
Nah. It was probably spuds..65p a bag or summat. I'm due a trip to the opticians. 
I'm paying 54ppl
It has gone up a lot......3 years ago i was paying 30ppl......i know petrol/diesel prices have also increased but not by that margin.....
Its got to stage where I wouldnt recommend converting an Omega anymore.....unless a)...you already have one and want to keep it and b) you do high mileage.
My next car will be a diesel again 
Undecided atm to which one.......but it will have to be estate/auto....maybe veccyC......maybe signum......kinda wanna stay vx...coz ive got TC card........but depends whats going for about £4k for a 3yo at the auctions :-/
I sort of agree, but...
You have to look at the difference in price. Around here petrol has just gone up again (yesterday) to 108.9ppl at the local garages (inc Tesco). I can get it slightly cheaper if I'm willing to do a 25-30 mile round trip, which seems to be a false economy!!
LPG at the same local petrol station is 57.9ppl, so there's still a fairly sizeable saving to be made!
I plan to keep the miggy for at least a couple of years and I do between 20 and 30,000 miles per year, including towing too. If the LPG kit costs me, for example, £900 to buy and get running then I can make that back within the first year!
That is, of course, assuming I can sweet talk Kevin (or anyone else!!) into giving me a little help with my conversion! I'm perfectly capable of doing the majority of it myself (fit tank, run pipework, mount units etc) but I'm a bit nervous about drilling and tapping the manifold and could probably do with a little help tuning the system! I'm thinking that for a few beer tokens someone will be willing to lend a hand!
