I keep hearing its the peace of mind of having your warranty in tact... well once your current warranty runs out, BMW will not offer CPO on your car due to Dinan... I have had my Jb4 for over 6 months with 0 issues and going in for service in a week or so.. granted I will be taking the Jb4 off and that is 30 minutes out of my day.
