Hi, I am planning to buy a 69-73 convertible (still undecided) in the US to bring to Australia. I plan to drive the car on a daily basis and want to know some thoughts on converting it to LPG. It won't be a show car but in nice condition. Will the conversion decrease the value of the car? Is there better conversions than others for these cars, or am I just being rediculous for wanting to mess with classic a beautiful car and save money on fuel costs? thanks
