Not sure what they should do with it other than leave it alone. This car is like the 73-87 Chevy/GMC pickups as they have been able to keep bringing customers in for a long time without having to do drastic changes to it.

If they change the styling to a non-retro design it won't sell as well.

If they make it a 4 door like the Charger it really won't sell.

If they make it a fwd, awd, V6 only, or anything too far from the existing drivetrain is now it will loose some of it's appeal.

The car could really use a nip/tuck styling clean up and a diet, but that won't happen.
