Hi
Back in the day when I used to work for BMW de-badging was done to keep people guessing wether it was a 1.6 or 2.5 litre engine but a quick look at the exhaust would tell you what it was
But some people do it for a cleaner smoother look on the boot / tailgate
Each to their own I suppose
I have never had 1 car in the 54 I have had that I have kept standard most have been subtle mods but I have gone a bit further with a couple I just like my cars to be different to everyone else’s
I must admit it’s not cheap to be different sometimes
Cheers
