I used this for my Cult Limo.....

A 1930 Model 'J' Dusenberg Town Car from the Matchbox range that Bertie mentioned.
I reckon it scales up well next to the Pulp Figures second hand car salesman and part time cultist, Shotgun Bob.
Dont know if that would work but it should help to decide which of the Yesteryear models should do you as this is listed as 1:43, so one of the biggest.
