Give me some wheels

So I love getting a ride to and from school from my principal, but I need some wheels of my own. I don't like the feeling of being stuck some place until someone else wants to go. I am looking for a 4 wheeler and there are a couple for sale in Nome. I know I need an automatic. I found an 08 Polaris, but I don't know anything about buying a wheeler. How much should I expect to pay? How much is too much? I just want to be mobile again! Someone please send me a wheeler 

until next time...
