Since I haven't been around much, here's a simple one for you.
Name the three jeep models since 1942 that do not have an alpha-numeric model designation. For instance the Universal Jeep came in several designations like CJ-7, CJ-3B, and CJ-5. The wagons have designations like XJ, WK, and such. I'm looking for three models that don't have a string of letters that those in the know use to name them.
