So far Dodge has only outsold the Mustang once in a single month with the Challenger and I believe that is likely due to heavily discounting them. For as many as you see they dont outsell the Mustang year over year. They have something cool going with their lineup but with their failure to update the Charger/Challenger that popularity is going to fizzle out in time and people will get tired of their cars and get tired of seeing their same car on every corner.
