coming from owning a couple of BMW MINIs and an AUDI TT, I've been blessed to have much less frequent visits to workshops for the intent of repair works with this m135i. It used to be every alternate month with the MINIs.
I'm also glad to have been offered and taken up the extended 3 years warranty.
I believe every owner has their own 'luck' but irrespective, it's the experience at the service centers that matter; the turnaround of servicing and repairs. Mine has been acceptable so far, as like most owners have been, I keep chasing them with follow-ups.
