Agreed, but lots of embassy sales are in the 7-series mix and corporate purchases tend to take place at the end of the year to maximize take deductions.

They're also one of the few sedans in the world that can support the weight of armor without massive work to the car and they qualify as SUVs according to the IRS if they're properly equipped as they "can" have GVWRs over 6,000 pounds, allowing major tax benefits to buying the vehicle (it still needs a bit of chassis reinforcement).

My father lives in Kosovo, and sends me photos of rows of them. I've saw a ton of them in Bogota, Colombia last year (in 2009). It was perhaps the most popular luxury sedan in the city, mainly due to the influx of Americans to the region, many of whom "think" they need security 24/7.

It wouldn't surprise me if 40% to 50% of the sales were to such entities. Either way, pretty good numbers, especially in this economy.
