this much is true...but to be fair, it offers the following:
1. Warranty protection (duration of extended warranty too)
2. Probably underrated (typical BMW #'s)
3. Maintains OEM MPG
For some, that makes sense. Those that drive leased cars, or use these F30's for daily commutes, need #1 and #3.
I'm on the fence since for $400 more, I could get a Dinan tune and "technically" have #1. Unsure if that carries over to 6 years/100k BMW platinum warranties.
