Help—purple 2005 atp!

I’m a new member here-Howdy! I just bought a 2005 ATP 500 that only has 340 miles on it, but it looks like it’s spent it’s whole life parked outside. The camo is in great shape-EXCEPT it’s turned a lovely shade of Purple and the black plastic on the bed and front rack is very weathered and has a silvery sheen. If you rub your hand on it-it will leave a black film. My question is- is there anything that can be done to fix the oxidised black plastic? and are the camo graphics painted on or are they a vinyl covering? How to Un-Purple it? (my Grand Daughters love the color, but I’m not sure I can get used to it…) Thanks in advance for any advice.
