I’d recommend you try “I’m not accepting the car as is, but I will if you have the calipers professionally painted to my ordered spec, to include the M logo as if coming from the factory” |
Personally, I would insist them to replace it with OEM red calipers, instead of having it painted. I wouldn't trust the paint unless it was done under factory conditions / using the original production process.
