how reliable is lpg in a disco?

looking at a 1997 3.9 lpg disco just need to know if there is anytging i should know and are they reliable , would you boys recommend
thanks mark

hi m8 both me and the mrs have v8`s on lpg and never had problem (touch wood lol) has it got a certificate with it? also if u do have it id recommend an lpg service . also the bloke who does our services cant stress enough that new plugs leads dizzy cap are imperative 2 running smooth on lpg. and at 41pence a ltr its quite economical to run and nothin beats the roar of a v8 .

ok thank you for the advice bud
