Ford says it sold more than 8,000 of its new 2015 Mustangs last month, its best November for the pony car since 2006.

When the final tally comes in, Mustang sales are expected to top 50% compared to the same month last year, says Ford sales analyst Erich Merkle.

Mustang is all new for the 2015 model year and November was its first full month of sales. The model saw some of the most dramatic changes in its 50 years, including a new turbocharged engine and a new suspension.

Dealers had only an average of an eight-day supply last month, which in the auto industry means that it is basically sold out. The average time that a model usually sits on a dealer lot is usually a little less than two months.

Merkle says overall, sales were up in every major region of the country, even the Great Lakes and Northeast that were hit by early snow storms.
