Say hello to Klaus Hammerschmidt, a 73-year-old retired entrepreneur from Germany that has received the keys to his 135th BMW car, a spanking new 507HP M6 coupe equipped with the Competition Package. Talk about a loyal customer... The 73 year-old's first bimmer was a 1800ti from 1963. If you do the math, that comes to an average of 2.9 BMWs per year. All in all, BMW said that Klaus owned 26 BMW M-division models, 29 BMW Alpina cars and 80 other BMWs. Hit the jump to watch a short video of Klaus receiving his M6.
