I am looking to order a 4-door 80th Anniversary, V6, Auto trans, with the Cold Weather group. Getting conflicting info from different dealers. One says you must get the convenience group if you get the Cold Weather group. The other says it isn't a must have. The 4-door preferred code guide from Feb 9, 2021 posted here on the forum looks like it is a requirement for only Sport S or Willys - not the 80th Anniversary. Looking to this group experience on this.
