I've always liked mixing the old with the new. As you can imagine I am a fan of the cougars... The 2009 Gullwig-America 300 SL Panamericana is a cougar of sorts and I don't mean Mercury... Enjoy... Another iconic vehicle is about to be reborn and brought into the 21st century. This time it is the Mercedes-Benz 300SL that is getting the make-over treatment (that’s the car with the batman-esque doors to you and me, or Gull-wings as they are known in the car business).
