Exactly. It's still a fucking Honda, and for the time/money spent on it you should have bought a Lexus. Similarly you can tweak wordpress all day long, in the end it's a blogging software.
Wordpress is the PHP of web publishing platforms. The barrier to entry is low, you can get decent results quickly, and it provides a great deal of power to the unskilled user. There are lots of things that it's good for; I'd say, in fact that in most cases it's all a company needs.
But it's really easy for it to become the only tool in the box, and pretty soon someone is in over his head trying to brute force it into being the solution to a problem that it was never designed to solve.
Now on the other hand, if you started with a British Mini...
