MINI USA reported sales of 4,320 automobiles in December, an increase of 23.8 percent from the 3,489 in December 2009, making it the most successful December ever for MINI in the USA. That 24% includes 575 Countryman. Not bad for officially not being on-sale in the US yet. You can see the full breakdown (via our friend Ian Cull) here.

For the year 2010, MINI reported sales of 45,644, an increase of 0.9 percent from the 45,225 sold in 2009.
