that will be my option when I change my car
range not important to me rarey do more that 200 in any day, and work next to an lpg station 
It's worth considering that filling with LPG is more of a faff than petrol. Often there are only 2 LPG pumps, co-located with petrol and diesel pumps, so you have to queue for them, wait for people to do their weekly shop in the attached M&S before shifting their cars

, etc. and then LPG pumps are out of service more often than petrol pumps, IME. Some also fill painfully slowly (10 minutes to fill an 80L tank! and some, with a 4 hole tank, are faster than filling with petrol :-/).
Just another thought for the melting pot.

I thought 150-200 miles range would be fine for me, and very nearly went for such a tank, but in retrospect I'm glad I fitted an 80L tank now.
