Build quality comparison F30 vs MB C250
BMW tech said F30 build quality is the worst he ever seen. Here is an example.
Hopefully, It could be an answer for excessive road and wind noise, rattle and creaks...
One of the photo shows BMW changed the location of clip holder in the last moment of production then didn't delete the old one.
1. Very thin sheet metal (compared to MB) with vinyl vapor barrier vs. solid sheet metal with riveted stainless steel inside cover (rubber sealant in between)
2. Recycled material for door trim (filmsy) without insulation vs. Reinforced ABS plastic with 3M thinsulate damping material.
