Rick9009, this is a bit lengthy!
There has been some very good advise given here but, what ever you do, you'll need to put in some time in order to first get rid of the oxidation. There are all-in-one type products that do this(romove oxidation and wax/shine the paint). You may need to do several coats expecially on the hood, roof and trunk lid.
Each year when I visited my FIL in Florida, I would wash/polish his blue S-10 PU that was left in the FL sun all year till I came down. He used the truck but never wash/waxed it. I would wash/wax for him. When waxing the truck, it would take several coats of what ever polish he had laying around(usually NU-FINISH liquid in the orange bottle). One coat down each side of the truck(as the sides of vehicles don't seem to fade anywhere near what the top portions do) but 4-5 coats on the hood/roof just to completely remove all of the oxidation to a nice shine. We would visit for a month as I to had a house in FL. During that month, I would wash/wax the S-10 several more time as well. And when I was done, this baby looked great! You could see youself in the paint and even the metalic would stand out.
I do agree with others here as-far-as they're preferd choices but, these products are also for their "Keepers", not vehicles that they're selling. These products are very good in keeping paint nice should they sell but, you seem to be looking for an off the shelf product that you can quickly prep your car for sale without ordering online.
Well, which ever product you choose, you'll need to use elbow grease/time to make the Elantra worth looking at. I have tried alot of easy-to-use products and they are "easy to use" but, not so easy to use on neglected paint. I don't know just how faded or neglected your Elantra paint is unless I could examine it first so, I'm not recomending any particular product. Just put in the time to make it ready for sale.
Also, back to the S-10. I didn't spend all day on this truck all in one shot, I would do things early in the morning while the rest of the house was waking up as I'm usually up much earlier than most. Then we would have the rest of the day as a family to do what ever we wanted to do. And too, because we were down in FL for a whole month, there was lot's of time to do lot's of things.
