decided to go for the advan sport, save a few bucks and tire profile less rounded as the others. not sure about the noise but the shop told me it is about the same as PS2.
needed the few extra bucks since I can't get rid of my E46 (may be it does not want to leave me). a few deals almost made but blew after all. so may eventually need to keep it and rent another parking space.
anyway, i have great fun to drive my cabrio with weather like this now in Hong Kong
