It was clearly a good month for SUVs over at Ford as the carmaker reported increased monthly sales by 3.5 percent.

While this may not sound that impressive, Ford was able to sell more than 87,000 F-Series trucks this month, with the average transaction price growing by $1,700 compared to last year –to $46,800 per truck.

Ford’s mix of sales was in favor of more expensive trim levels. Despite selling only 1,711 Lincoln Navigators in March, 80 percent of them were Black Label and Reserve models, boosting the average transaction price by $25,600. In addition, Navigators spent an average of just 10 days on dealer lots before getting sold.

The demand is also strong for the all-new Expedition which sold 5,653 units. 26 percent of buyers went for the range-topping Platinum model, raising the average transaction price by $11,500. Models spent an average of 17 days in dealer lots before finding a buyer.

Ford now claims that it has the highest transaction price of any full-time carmaker, averaging $36,300 per vehicle.

Only the Focus and the GT supercar saw their sales increase on March in the rest of Ford’s lineup. Lincoln also saw declines on models like the MKZ and Continental, with the latter being down 14 percent.
