Every once in a while, you see a nice concept come out of Detroit, what your talking about (a nice car with 50's styling) Ford did a few years ago with the Ford 40, a coupe styled like a 50's 2 door Galaxy with glass roof. I saw it at the New York auto show and it was real impressive - for a Ford. There have been cars that have been steadily coming out the past few years that have gone back to "vintage" styling,
Jaguar x-Type /XJ
Thunderbird
Mustang
Nissan 350 - not really vintage or retro but back to it's roots
These are the only ones i can think of off the top of my head. What GM did with the SSR & HHR is a joke.
But it seem with all the foreign vehicles americans have been buying over the lsat few decades, detroit is finally making products we may actually want. Dodge has to be given credit where credit is due, they basically brought a car back from the 70's that DIDN'T sell well (compared to competition Mustang & Camaro) but had "something" (style) and just made it as if today was 1970.
No matter how many deposits were took, no matter how many of us knocked down the dealers doors willing to give Dodge money, This car will have a shelf life and that's what companies are concerned about - how long can we build this thing while it makes us MONEY. Chrysler is being cautious now, let's see how this Challenger goes, they've already got Mopar stuff for it that's nice, Colors will come & if they don't - trust me, someone will paint theirs Plum Crazy or Panther Pink (Foose or Trepanier probably has one already to go) but look at it this way,
They could have brought back the Challenger from the late 70's to early 80's, a Cordoba/Charger/300 from the mid to late 70's or the Shelby Charger.
Bottom line - talk with your wallet.
