What is “large” about any of those vehicles? 35 years ago they were called compacts. No bust on you jjotto, but if I want a large sedan, I’ll rebuild an ‘82 Caprice Classic...with a Big Block V8.
The standards of comparison in large lux sedans are the MB S-class and Lexus LS. They’re about the size of the old Chevys, although they may not look it.
