Auto spy photographer Brenda Priddy spent a weekend talking to Mustang experts and insiders, but no one could help get a line on this spotted 2010 package/edition. Priddy says the single tailpipe and rear emblem indicate that this is a 4.0L Mustang, but the unique stripes and body-colored side window louvers indicate it's not part of the ordinary run. One possibility is that it's the 2010 Pony Package with a few extras. Perhaps something totally new. Whatever it is, it's another new look for the 2010 'Stang.
