has anyone got any experience of running an a8 on lpg fuel please? I would appreciate any input,especially a good installer in the midlands area.i have been quoted £2,200 for a sequential system with a tank in the boot of 90 litres. This was by a firm in coventry. It sounds just a little bit expensive.I had anticipated something nearer £1,800. Iknow some people are taking their cars to Poland to get the job done but that seems a major hassle. Thanks , john.
