When we talk about Japanese luxury cars of the early 1990s, we usually mention the Lexus LS400, the Infiniti Q45, and maybe— if we’re allowing smaller front-wheel-drive machines to fit our definition of genuine luxury— the Acura Legend. Once in a while, maybe some edge-case type might thrown in a reference to the Mitsubishi Diamante, but one car that almost never comes up in the discussion is the Mazda 929. Why not? It’s a big, comfy, rear-wheel-drive sedan with healthy V6 power. The late-80s/early-90s 929 is just about extinct these days, but I managed to spot one in a California self-service yard a few weeks back.
