Why are cheap cars unattractive?
I understand why inexpensive cars aren't mind-bendingly beautiful. That'd require top designers and fancy production techniques.
But somebody designs these cheap cars, and I can't imagine the second or third string designers at big auto companies have really horrible taste.
After all, if you sell a million cheap cars, adding $1 to each would enable a million dollar design at minimal per-unit cost! And maybe the result wouldn't be stunning, but why should it be ugly, or even plain?
....unless big auto companies deliberately uglify their cheaper cars to protect the premium edge of their more expensive ones. But, if so, then why hasn't that encouraged smaller manufacturers to make nice-looking cheaper cars and gobble up that end of the market?
I'd ask the same of many other realms: why should ugly be that much less expensive than decent-looking, unless human beings are so terrible at design that only a handful of (very expensive) designers can create non-horrendous products?
Update - I think I may have answered it. See the comments, below (which include an interesting but, to me, slightly opaque posting by El Seth)
