land rover specialists in somerset

hi folks, I'm looking at buying a disco from A & d land rover in somerset, now it turns out there an lpg specialist, which is just what I'm after!, but I couldnt quite make my mind up whether they could actually deliver the goods, after speaking to them, or whether they just talked the talk????

Anybody on here had any experience with them, or know of any thing??, before I part with any cash!!!!!!!

cheers
