I'm looking for a new car and know Japanese is the way to go and for a young man, the only Japanese that I can see myself in is the IS200 (Civics r ok... but NAH!) If not IS200, then its an A3 based on parking space availability in london, and long living looks (like golfs, not much changes shape wise so could keep for a decade or so). Any one I get HAS to be able to cope with an LPG conversion, this thread has left me with mixed feeling tho! Overall from everybody's posts and personal experiences, would u guys recommend the conversion or not for Lexus IS200 (Automatic)? The power is the next issue, cause I want a little performance... what modifications would u guys recommend (if any), and this is ASSUMING they can be done if on LPG conversions! Thanks in advance
