Nooooo!!
Plenty of people are driving powerful cars with highly strung engines, and I imagine plenty of them aren't waiting 'till the oil temperature is up before they rev it, you wouldn't expect their engines to go bang.. - even TVR wouldn't manufacture a car that crazy
No car should ever explode like these are, at such low mileage, no matter how badly they're treated (save removing all the oil, or over-revving beyond the limiter), especially a BMW.
They'll sort it eventually though, hope they stop being so *****ty to the customers tho
later
