I've worked on many Volvo cars. The thing still is how bad the paint is and what you are trying to accomplish. If I were to only use what you have listed, I would start M101 with yellow pad on Flex 3401 then move to M205 on green pad. If it were my personal vehicle, I would use M105 on orange pad in the middle if I was striving for perfection. Of course, this is just what I would use with that you have listed. Be sure to clean your pad often.
