I would like to e-mail you, but couldn't find an address. Should you wish to impart wisdom to a young potential E46 owner, please drop me your address at smells4u@pacbell.net . I really found your ideas and numbers fascinating (even thought I probably gathered only about 1/7th of what you were talking about). Likwise, I'm very interested in Dinan products and would like to have someone to ask layman questions on their products to. Thanks and hope to hear from you...
