Attention--Can I get some help here, please?

Hey there, I don't post often but I am in need of some help. I am looking at buying a 2005 YZ450F for a really good price. Bike is completely stock. Any issues with this year that I should be aware of? One other issue--seller bought the bike out of state at a repo auction. He has title in hand.

A little background on myself, currently have a 96 KX 250, piped, ported, and polished. Has little to no bottom end. Enjoy desert riding, trail riding, and the occasional track ride.

thanks
