absolutely, and also the fact that they are not sleek, streamlined machines. the Millenium Falcon actually looks like a fairly run-of-the-mill boring freighter ("what a piece of junk!"). it's only our affinity with it that makes it so cool (and its speed, obviously). same thing with many of the other ships, the Y-wing, for example, as well as the Star Destroyers, the Jawas' crawler, the landspeeder, Slave 1 etc. they all look like they've had bits added and taken away over their lifetimes. Tie fighters look functional, and even the sleek X-wing looks pretty ungainly when parked in a hangar.
I always liked that, and is one of the reasons I never liked Star Trek that much. the main ship in Alien is a great film 'spaceship' in my opinion. it looks really functional and boring, exactly as one might look in the future.
contrast those with some of the cartoon machines in the first three Star Wards films: Amadala's silver ship being the best (worst) example.
