Folks, I'm seriously thinking of converting my VYII Wagon to gas (for obvious reasons!). Are there any tips, gotchas or other bits of advice or experience that anyone can pass on. For instance... I've been quoted about $3500... that sounds a bit steep.. but is that normal? Is there such a thing as using "Holden std parts"? Do any Holden dealers actually do this conversion, or is it always 3rd party outfits? I'm told that the std place for the tank is in the spare wheel well... is that normal also? Will this give me a dual-fuel car, or will the petrol tank then be redundant? Thanks for any and all input. Joachim.
