BMW has a commercial with the theme of not accepting substitutes. Accept nothing less than what you want and all that. Presumably, they’re trying to talk people out of taking John Tierney’s advice of buying a Subaru WRX rather than a BMW with similar specs. What I find kind of amusing, though, is that if you read the small print across the bottoms, the precise models that they’re showing are not available in the US. So if you go to your local BMW dealership, you’re accepting a substitute.
