You really make that much of a saving? That sounds like it would be cheaper to run than my current Volvo C70 T5 2.3 turbo!! Does it just drive as normal when switched on lpg?

Hello, I am considering buying a Range Rover v8 on LPG but I am really not sure about how much this would cost to run with using LPG?? Also, I am looking to find a typical repair bill for a Range Rover. Has anyone got a V8 LPG Range Rover and could you tell me how good it is? Any info...
