Okay, most of the posters on this thread have been from non-US countries. NooDle, we've talked about the difference in equipment standards between the US and Europe, so this will come as no surprise to you.
Dsemaj: In the 80s, things like your Bluebird (or the US counterpart, the Maxima) usually came with the following as standard equipment, at least:
Power steering, power brakes, front discs, automatic transmission.
It's just a function of the US market - you must have the same or better features to compete in a class, its as simple as that. Often, makers will "one up" each other with a new feature as standard - and within two or three years, all the class will have it as standard.
If the car didn't come standard with all of those, it was a negligible cost option or included with a higher trim level. I do know that one of Nissan's big selling points in the 1980s was the fact that *all* their cars in the US came with power steering at no extra cost (at one point) and a secondary point was that a number of their cars had ZF-built rack-and-pinion steering systems lifted directly from the 3-series BMWs - the 300ZX being the best example of this.
All the GM, Ford, and Chrysler midsizers had power steering as a matter of course (thanks to the Japanese competition in the 70s). I think you *could* still get a stripper Toyota Camry with a stick and no power steering up until 88, but it was a special order model. The Cressida was never (IIRC) available without power steering. The Honda Accords *all* had power steering by 88, and I vaguely recall it was standard by 79.
