Excellent observation. Brand dilution is delusion.
Someone at Daimler partook of the new religion in Marketing and effectively proselytized the notion of "brand cannibalism" and execs there bought into it.
If Cerberus is the real deal, they should flinch at this. Sure they produce similar products and maybe a little confusion, but it also provides an opportunity to provide slight aesthetic variations to body, trim and finish to entice fence sitters (if they're vacillating on any particular minutia for the body, interior, lights, etc).
Additionally, it'd create some pretty decent buzz and free
PR.
They'd be able to really hammer the practical family demographic AND ......... re-introduce 'Cuda action!
Creating a symbiotic synergy of one masculine car at plymouth, and one family car at dodge.....
it's a mopar love fest. Also, it would lend credence to the T&C at Chrysler (if the voyager is even still available).
that's my two cents
