The Magnum may be lower volume entry, but I'm not sure you can call a wagon like that a niche vehicle. Stuff like SSR, Prowler, et al, are nice, but they're not much good other than for occasional use. Those are what I'd consider niche vehicles. Magnum is offered in V6 and V8 versions, so there's some utility there. The market is moving that way, from tall SUVs to crossovers to wagons. Given Subaru Outback to Audi Avant to Malibu Maxx, there are more than a few wagons out there. The market is likely to grow as the wagon sheds it's "1975 Brady Bunch" stigma and is looked at as a sporty type of SUV. With the Magnum V8, here's a vehicle that's hauls goods AND hauls a$$ ..not to mention offering a nice chopped and channeled profile. How can it lose?
Word on the street was that Charger will be Dodge's 2-and 4-door entry, so the Magnum is only offered as a wagon here.
Chrysler (Magnum and 300) and Ford (Mustang) now have somewhat practical and affordable vehicles with the classic American V8 driving the rear wheels. GM is the only one of the Big 3 not in that race, which I think it gonna bite 'em in the behind. There's GTO and CTS-V for the near-wealthy, FWD 4 bangers Ion Redline and Cobalt SS for the 18-28 crowd, and absolutely nothing for the middle-class, 28-40 crowd. (Impala SS S/C? ..almost but not quite). These guys really want a practical performance car, myself included. Dodge scores 1, Ford scores 1, and GM gets the big 'ol bagel.
