Spoken language and literature alike have a license with grammar.
Sentence structures can be manipulated, words and phrases elided, all in an attempt to convey the right emotion.
That's the Ferrari? means quite a different thing from the "grammatically correct" Is that a Ferrari?
The latter is essentially a request for information: Yes, or No.
The former, loaded, possibly implies "You call that a Ferrari?" or even, "I don't call that sort of thing a Ferrari" depending on the contextual emotion.
Similarly, it is very difficult to create the kind of "effect" that the sentence
He went through all that just to go to Columbia?
evokes in the listener. Note that this sentence is not a question. It's an exclamation, like Really?, implying something like
"I don't see how going through all that is justified just to go to Columbia, period."
