this only me , but lpg gose up and down in price so much its a joke.
i went to gas in a ute in 98/99 and lpg was 26 per litre and with in
a couple of months it moved up to 55 near 60 , nearly cryed.
lpg cars need aspecialest to sus then out all the time as any minor probles will turn in to monsters , depending on the motor man you use.
They need regular maintenance all the time , twice as much as petrol.
And truly now days theres that many lpg gas cars around that you would more than likly pick one up cheaper than a conversion , and thats not just very used taxis iether.
Price around is all you can do , This is just me but Lpg is great for buliders . buses ,taxis and other people who earn aliving out of ther car , and can write of the in tax ,, but for jo blow, it ait worth it .
Noted it ait the most silly thing you could do , but it is handy to have that extra tank to double you distance on long trips.
thats just me and its your car.
