The market shift to crossovers pinched dealers for traditional luxury rivals BMW and Mercedes-Benz last year, leading retailers to lobby for a better product mix this year.
Otherwise, dealer council chiefs say, they're missing out on sales.
"We would have liked to have had a lot more SUVs to sell," said Mercedes council head Ken Schnitzer. "The market has moved further toward that segment than anyone thought. It's really all about trucks."
Mercedes did a "great job" in 2016 of shifting production to trucks from cars and increasing allocation of SUVs and crossovers to the U.S., said Schnitzer, who is chairman of Park Place Dealerships in Dallas. But demand for SUVs and crossovers still is outstripping supply, he said. The shortages are across the brand's entire truck lineup.
Dealers have asked for another increase in truck allocations in 2017.
"These vehicles have been well-received all over the world, so we're hopeful they'll be able to meet some increased demands," Schnitzer said. "But we really won't know that until the first quarter."
