1st Option - If they're not too deep (just surface scratches) try some polish. But don't polish too much or you could remove the car's sheen
2nd Option - You could purchase a scratch pen from supercheap or buy some touch up paint from Jeep direct. You're somewhat luck you have a black car, cause the colour wouldn't be too difficult to match from the supa cheap range.... I think the supacheap pens are only about $20, but the Jeep touch up tins are about $70 based on a quote I got a few months ago.
3rd Option - Get a proffesional to come look at it like whatscratch.com.au - Google is your friend when it comes to finding scratch removers
The only other option you have is to leave the scratches, and treat them like 'scars'....
