My three wishes
1) Mundane mid 50's four door Chevy Sedans. The kind regular working folks drove. Not Belairs. Not two tone. A 210 would be perfect. A 150 fine. Maybe even a station wagon (not a Nomad or Belair). Prefer 55 or 56, but will gladly take a year earlier or later. 1/43 scale is fine, but make them decent models.
2) Mundane mid 50's four door Plymouths. Same as above. Except models become Savoy, Belvedere.
3) Mundane mid 50s Pontiacs or Oldsmobile. (The "or" is only because I am allowed three wishes).
