Hi, I have a 1999 BMW Z3 1.9cc convertible running on petrol. Can you please give me the pros and cons for the conversion to LPG. Would you recommend such a conversion. Some mechanics claimed that there are no disadvantages, while others told me not to convert as BMW cars will require frequent injectors or spark plugs replacement. I would appreciate your opinion. Thank you and regards. Noel Portelli
