Meguiar's Scratch-X works very well for minor scratches, and if the scratch is into the clear but not into the paint, you can sometimes wet sand it down using 2000 (yes, two THOUSAND) grit or finer, then buffing it out using 3M or Meguiar's cutting compounds, then finer buffing compounds to bring it back to brand new.
If its past the clear, you won't be able to wet saned it out all the way, but you can use a color pen to fill it in, then wait a day to fully cure and do the same sanding process above.
Of course, if you're not comfortable wet-sanding your brand new vehicle, just hit a reputable detailing company where you're at and have them do this very same work. Be prepared to pay for it though, this service is not cheap to do!
I did a lot of graphics work with a detail shop a while back and got to see the process of doing all these types of repairs (including fixing leather tears and carpet repairs in vehicles, as well as paintless dent repair!), and its an awesome skill to have! I've done the above process on my 4Runner already, and am comfortable in wetsanding vehicle paint and buffing it back to better-than-new condition, but I've had lots of practice doing it on other vehicles that I didn't care much about!
Still, try using Scratch-X to at least get rid of some of the scratch, you may be able to live with it once you do so. I will actually use my 3" foam buffing pad with Scratch-X nowadays to quickly cut a minor scratch out of the paint without even thinking about it, but wouldn't suggest you try this on a new paint job!!!
