People that take used car parts for building other sorts of machines, do it for entertainment, and do really enjoy it, despite this endeavor would not precisely bring them a monetary reward; perhaps just the recognition from others, who like to see bizarre things going out of pretty common things, like cars are; but people that choose used car parts to build, for example, a functional 'droid', don’t do it for the recognition. They do it for fun, because it is funny to play around with things that one ‘should not play’!
That's a very strange way in which can be used used car parts; indeed, a very strange way, because the most common is to use used car parts to fix your old car, naturally. But still there are some persons that give to used car parts yet a different utilization, and construct with them ‘arte nuevo’, very expensive, and, like the functional droid, quite bizarre.
Some others find nice to decorate their livings, their rooms, their spaces, with used car parts, and think it is cool to have the used car parts as ornaments. They buy this ‘arte nuevo’ done by bizarre artists, and get a lamp that used to be a steering wheel or a chair that before had hit the road.
