exactly what did i just buy?

alright guys heres the deal, last night i went tot a guys house to looks at a supposed 1999 xplorer 300 4×4, but when i got there i noticed it had no oil tank for the oil injection and i looked again and no reads..wtf this is a four stroke. so i bought it cause it was in great shape and i ran home and jumped on the computer and from what i can tell i have a 2001 Polaris Sportsman 500 with xplorer 300 plastics. im hoping you guys can narrow down exactly what i bought.
