Exactly ^^^
A diesel M Car and a diesel M5 are two different things.. Just like M Sport spec on most models (like mine), it doesn't make them an M car. Even though many a 'M badge wearing berk' in their 318i will disagree
'M' Car
Definitely not an 'M' Car
No different to saying a 2.0 TDI S Line is and S model...
Things my balls are safe for the time being..
