When does CPO period start?
Assuming a CPO hits 50k miles before four years is up, how does MB know when the CPO period officially starts/ends?
For example, if I have a 2015 with a 1/1/15 in service date, but it hits 50k miles on 6/1/18, how would MB know that CPO kicks in on 6/1/18? I get that if I brought it in for a 50k service, they would know. But let’s assume I do the 50k service myself.
I’m getting different answers from MB dealers. Some are saying CPO starts/ends based on in service date, while others say if 50k is reached before four years from the in service date, CPO kicks in then (but they aren’t clear on how they determine official start date in this type of situation).
Hopefully I’m being clear, but if not, let me know. Appreciate any insight.
Thanks.
