I wrote this several hours ago but the message board was having some problems so I wouldn't submit... Let's see if it does now!
I think people will accept it better than they would if it were a remake. Hopefully, if the show is made into a series and last awhile the car will be changed some something sleeker. My biggest annoyance is the emblems and the teaser didn't alleviate my concerns over this being a glorified two hour Ford commercial including "limited commercial interruptions, brought to us by Ford.
There probably wasn't a whole lot of choices since GM probably wasn't interested, especially after the annoyance brought about from the original series, plus they have a deal with Paramount, besides that, there aren't a whole lot of cars with bodies that would be durable and affordable on a TV budget to do stunts seeing as most cars now have fiberglass bodies. That, aside from Ford probably giving NBC a very good deal on the cars, is a big reason why the Mustang was likely chosen.
