My experience of a BMW 530 SE has been mixed and at times disappointing. The paint work chips easily on the bonnet and doors the water based paint is just poor quality. When i com0lained to the BMW supplier there was an acce0tance that this is a problem but no willingness whatsoever to make address
Then there can be problems with the rear suspension mounting mine sheared off at speed on the motor way and shredded my run flat tyre it was terrifying
It took 2 days for a replacement tyre to arrive
So my advice to BMW is to improve your quality and build safer vehicles
