What should I be lookin for ?

Looking to get a grom for learning and cornerstore runs , Saved up a little over 2000$. I plan on doing wheelies on it eventually so I don’t think I’m tooo concerned on it looking perfect but around what year and mileage so I be aiming for with a 2k budget and what are the main things to check for when buying used ? Don’t have much experience outside of a couple 125 cc dirt bikes so sorta clueless when it comes to bikes
