Girl L is Miss America of 1954, Evelyn Ay Sempier, sitting in a 1954 Nash Metropolitan.
I don't think I see a Nash Metropolitan dashboard among the thirteen, so I'm guessing the connection is the girl. Dashboard 4 looked like it could be from a Fiat 124 "Eveline" Coupe Vignale, but the steering wheel wasn't right, so I thought it might be a tuner modification. Sure enough, the dashboard pictured is from an ad for a 1969 Giannini Vignali Eveline which is/was for sale in 2012.
So, pictures 4 & L, with the connection being Eveline/Evelyn.
