The fact that BMW’s sales are down compared to January of last year should come as no surprise. These aren’t just cars, they’re luxury goods. What’s significant is the breakdown of model sales. The 3-Series and X5 sold 5471 units combined—44% of BMW’s entire sales for the month of January. Add in the 2596 units of 5-Series sold and between those three models (3, 5, X5) you have twice as many cars as the rest of BMW’s lineup combined. To wit: the 1-Series sold 716, the BMW Z4 roadster and coupe sold 45 units (down from 363 last January), the putrid X6 managed only 266 sales and the spine-crunching X3 registered 394 sales. And then there are the 6-Series (304 sold) and the 7-Series at a whopping 23 units. The explanation is that the next-generation 7-Series hits BMW dealers in a few months; same for the next-gen Z4. It’s not all bad news for BMW though—the M sub-brand had a record year in 2008, with its sales rising 50% over 2007. Dealers report that the boost in sales came from offering to throw in a free tub of hair gel with each sale.
