Ladies and GentlemenMr. Porrino I think your aim was to gain knowledge by asking this question. Please allow me to inform you that it has never been Cadillac versus LaSalle. They do not compete, contend, or vie for affection.
Sure there are opinions and preferences but when we travel on the road it is Cadillac & LaSalle together against EVERYONE else.
The following are excerpts found in the wonderful book, LaSalle: Cadillac's Companion Car by Ron Van Gelderen and Matt Larson.
The LaSalle was not a little Cadillac...."It is an entirely new car for a new purpose to fill a new field of usefulness".
(I am currently finishing a rarity value guide for LaSalle automobiles)
