Gang, Relative newbie here (to this forum, not to Ferraris) looking to bone up on 550s as I dip my toes into the market. I am looking for a nice, clean, no stories 550 in TdF Blue, Grigio Ingrid or Silver Metallic. I'd like to stay south of 100k if at all possible. What is considered the definitive guide to these cars for someone looking to become an owner? i.e. the difference between model years, options available, problems to look out for, "problem" model years (if any), etc. Any books, publications I should pick up? Any suggestions most welcome. ketel
