Well it's not exactly surprising that anyone would make general comparisons between BMW, Audi and Mercedes since they're all premium German brands with excellent reputations who make many similar cars in many similar segments
And to each their own. Personally, I can't stand Audis because I think they're chintzy, bling and a bit ugly. I find Merc has an image that's older than I like to think I am and right now, the 3 series is the right car for me. In a couple of years when I get my next car, that might not be the case so I'll be doing another earnest comparison between brands to find out what suits me best
