Mine was a dealer transfer and it was supposed to have ~300 miles on it. I went to pick it up and it had 600 miles and it was dirty on the inside. We got them to detail it, fill it with gas and got the road hazard warranty, interior warranty and some paint protection thing on it for nothing extra. I figure the warranty BS was about $1000 so I was fine with it.
The paint protection thing was pretty cool also. I was supposed to be some extra clear coat protection thing they put on and was supposed to help with UV light and add some minimal chip protection. I don't know how much it will help but I have washed it a few times with dish soap and the water still beads up on it (they told me I wouldn't have to wax anymore, we'll see about that though) but so far it has been good. I got some bird crap on it and it wiped right off with a paper towel after sitting on there for a day or two.
Sorry for the long winded answer
