What's the point of having a big car with a tiny engine?

You won't get great performance.

You won't even get great fuel economy. To move mass takes power. To use power takes fuel. A small engine needs to make the same power as a big engine to provide the same acceleration. While it will use less fuel at idle, any time you need to accelerate, an overworked engine will use much more fuel than a bigger, understressed one.

If all you want is the looks, it's pretty easy to stick a few hundred thousand pesos worth of ugly bodykit onto a small car to make it look bigger....
