375 inhabitants of Canada purchased or leased a Mercedes-Benz GLK350 4Matic in October. That takes the total for 2009 over 4,000. Which means Mercedes-Benz is only missing out on 33,110,000 other potential buyers. Subtract the unlicensed and we’re still left with millions of consumers in just one country who either have not yet or will not ever purchase or lease a Mercedes-Benz GLK. Yet the GLK is Canada’s most successful small luxury SUV. Clearly we don’t measure success in products like this the same way as we do with, say…. Coca-Cola or Windows 7. So how does Mercedes-Benz do it?
