First car buy

Hey, so ever since I was young, my dream car has been the hummer so owning the Hummer fleet completely one day is the goal (when I’m older of course), I’m pretty young and really would like to get the H3 or H2 for myself as my first ever car. I found a few but the problem is the dealerships/sellers have either a bad rap or are kind of very sketchy. I would prefer to buy cash from a private seller but I’ve been scarred before when when my mother attempted to purchase a different vehicle. Trying to save back up. I guess my question is would yall know any reputable dealer willing to work with a down payment under $4k for a 07+ h3 or 03 h2 in the state of Georgia. Or anyone selling for that amount?(gotta ask 🤷🏾‍♀️). I am still actively saving and would like to have money put aside for “paper work” of owning a vehicle.
