This is Chrysler remember. And a sport/performance car. 2022 sales was the 6th best of the car's 15 year run and the 3rd year in a row of increased sales.

And there are those that disagree with your assessment including both media and the manufacturer:

"The Dodge Challenger is very, very old, but it doesn’t matter. For the very first time since the car emerged for the 2008 model year, Dodge has sold more Challengers than Ford and Chevrolet have sold Mustangs and Camaros.

Some will chalk that up to the chip shortage, and it’s quite possible Dodge and its dealer network have responded better to it than its crosstown rivals, as brand CEO Tim Kuniskis recently suggested to Automotive News in an interview. But to Stellantis’ own credit, the Challenger’s ascendance relative to the competition has been a trend for roughly half a decade now. The Mustang and Camaro have only slid in sales since 2015, when Ford’s numbers peaked. Incidentally, 2015 was the year the current-gen Mustang hit the market.

Kuniskis is adamant that being the segment leader is not Dodge’s aim, but rather a welcome prize for weathering the supply chain storm, and a sign his team is in tune with what muscle car customers want: a sense of community, supposedly."

I agree with CEO Tim Kuniskis.

This is what Chrysler does and has always done. When I went to business school, back around 2005 or 2006 we had an auto biz class and the professor was a retired industry vet. We got talking about Chrysler and he nailed it. "They're doing ok now, but give it a couple years and they'll be in dire straights again (and like clockwork they went bankrupt again). But he said they historically did their best work when their backs were up against the wall facing liquidation, and like clockwork again they did come out with some pretty good products that saved the day.

Now it seems they are about to create their own hurricane and impending survival plan
