It does matter, it is a 2006. Ask them to print you a “Warranty Vehicle Inquiry.” Since you didn’t buy the car they they will probably tell you no, but it’s worth a try. It will have all the dates listed for everything. I bought my 2006 X3 as CPO. My in-service date was 01/17/2006. On page 2 of the report it shows “NO COVERAGE” as of 1/17/2012 (6 years or 100k - which ever come 1st). Keeler can’t change BMW’s rules, they are only a franchise. Who did you talk to there?
