Toyota tried to position Scion as it's "college student entry line" of vehicles. Separate from other Toyotas, even with a separate sales area on the same showroom floor. The first two generations were some interesting cars (I termed the original Xb sedan "X-Box"), but then sales fizzled and many dealers wanted that showroom space back for other Toyotas.
DeSoto was, toward the end, competition for Olds and Mercury, I suspect, but could encroach into Dodge Territory at the lower end, but with Chrysler size and flair. Not quite the same as in the middle '50s.
Funny thing, to me, was that when all divisions had a version of the Gen I Hemi, each carline's engine had its own distinctions. Plymouth had no V-8s, until '55. Dodge had the smallest versions. DeSoto had the "long stroke" versions. Chrysler had the largest CID and power versions.
In the earlier '50s, DeSoto had the 8-passenger factory limos, which were also used for upscale taxi cabs.
In those earlier times, the product lines of Chrysler exactly mirrored those of GM.
Chevy - Plymouth / Pontiac - Dodge / Olds - DeSoto / Buick - Chrysler / Cadillac - Imperial.
FUN times back then, keeping up with what was what!
