i live in Tampa and looking for a fellow enthusiast who knows of a good indy shop or would like to help me ( which i am willing to pay) who has performed a water pump change and head gasket work on my car. If you are in Tampa Florida and know how to do this it would help greatly. you can PM me or respond to the post, The Smart is a 2009 Brabus Cabrio with 115K on it. She drove it and said it blew some white smoke when cranked. I drove it afterwards and it didnt do it. I then drove it an it bucked and white smoke poured out then it stopped and drove find. So I am thinking it is a head gasket and most likely the water pump has gone in it.
