Which answers can you eliminate?

I have moved this to a thread of its own. Please do not ask a new question, as a answer to someone else's, you may never get any real answer that way.

Also you have to wait for an answer 3 min is not going to happen it can take often a day or two for an expert to review your answer, and it can even take a couple weeks to get several good answers.

But as a note we don't do your home work, if you wish to tell us what you think and why we can help you with it.

This is an easy question. Think about it. Does it really matter how old the car is?
