No such thing as a dumb question first and for most. Is there any way you can take some close up shots on the paint and overall condition of the car in direct sunlight? We need to see how bad or good the paint is in. Normally when a car is purchased they have it "detailed" for you and scratch the clear coat to all hell. This is why others seem to look better, they have removed (or hide) the scratches so light reflects better.
Example: My mustang looked like this "detailed" before I learned to polish and just take my paint to the next level

This is how it looks after I've practiced enough and found the sweet spot (no wax or anything just bare clean prepped paint)

That is what we mean by prep, remove the clear coat scratches so the light reflects off the paint with out being distorted. Scratches cause a haziness/dulled reflection. Then polish the paint (also called 'Jeweling') to enhance the paint. Not really sure how to describe what polishing does to the paint. But think of it like this, you take old jewelery to be cleaned and when you pick it up and look at it, the edges and surface "dance" in the light. Same thing (kinda off).
