With due respect to your particular 190 SL, they weren't really held in the highest regard in their day. Looked good, but otherwise unsophisticated and underpowered. Values have recently shyrocketed, to be sure, but that is probably more a reflection of the value and worthiness of the 300SL than the individual merits of the 190SL.

Ditto on including the unparalleled 600 Grosser and 300SEL 6.3 sedans.
