>>12969I think it first has to do with the vehicle being aesthetically-pleasing, which is a natural human attraction. In our culture, lower and even moderately-priced items won't be particularly aesthetically-pleasing, with quality and functionality being the most important. As you go up in price, aesthetics gradually become more important, while quality and functionality become less so. There is a medium to medium-high price-point where something is both good quality with good aesthetics. But even then, aesthetic choice is limited due to the market not particularly valuing aesthetics to begin with. Only at the highest price points can the aesthetic of something be truly customized for a person. If you own an object such as this, you implicitly have a lot of money. Many people think money gives status. The emotional component comes in, due to people's greed, anger, and delusion, thinking that money and status are important and need to be attained. Sexual appeal intermingles with this, as a means to strengthen and promote the illusion.

(In addition, the rust aspect is funny because it reveals the superficiality of it all, as a lack of regard for quality (and possibly functionality) is apparent almost directly within the aesthetic (just give it a few days) (i.e.: rust ruins quality, functionality (over time - most believe rust leads to holes), and aesthetic all at once.)
