"We've certainly benefited since it's been launched," Hult said. "We're pretty happy with it."
Another dealer who declined to be named said that while the launch is going well, the E class hasn't been the blockbuster it has been in the past when a redesigned version came out. He attributed that to the market's shift toward SUVs.
Some customers and dealers have reported significant waits getting their E classes equipped with the top-of-the-line Premium 3, or P3, package, which includes the brand's most advanced available semiautonomous driving features and head-up display.
Michael Pacifico, a longtime Mercedes customer in Las Vegas, said he tried to order a P3-equipped E300 early this summer. After being told there was a problem with availability for the head-up display, he eventually was able to order the car with delivery slated for January. In consideration for that long wait, Pacifico said, he received a "nice discount, rare with a Mercedes."
Exler said he couldn't comment on the situation with the head-up display but noted that Mercedes has experienced capacity constraints at the supplier level that has limited the availability of some features. He called that "unsatisfactory" and said it leaves "untouched opportunities in the market" but that it's a better problem to have than weak demand.
Mercedes-Benz of Des Moines has had some customers waiting for vehicles with the P3 package, Collinet said. The dealership has been able to work with Mercedes-Benz to extend leases on their current vehicles. Other customers have chosen to buy an E series without the P3 package.
"Typically, they're pretty understanding," Collinet said.
