Does the car run okay on LPG? I've heard LPG is suited more to V8's than some other cars.
I had LPG installed on one of my old Saab 9-5's. Economy was 26mpg on LPG compared to 30mpg on unleaded - can't remember what this saving converted to at the time based on cost of LPG to cost of unleaded. I saved nothing over all with my LPG - cost me a fortune in problems. LPG system cost me £1880 - sold the car for less than that a few months later.
