What kind of pos did I buy?

I don’t know atvs at all. I was told was a 300 only to discover it’s a 250. It has a 5 speed and reverse .
I tried to decode the vin and I think it’s a 1985 trx250. The pictures online show a fourtrax but it doesn’t look like mine. Any help would be appreciated, I’m trying to decide if it’s even worth trying to fix.
