I agree with Stealth. The majority of debadged BMWs you see in Europe are of the low displacement variety. I go there a lot and travel with local car guys; their typical reaction to seeing a debadged car is to look at the exhaust. 99% of the time it's a dinky single pipe, indicating there's not much displacement under the hood. They (at least the guys I've worked with) chuckle at that, the assumption being the owner is 'posing'. Now and then you'll see a more expensive model debadged, but it's rare.
