Need some advice (Car buying content)

Im finalzing the purchase of my bosses 97 Ford Ranger, 4 cyl, 5 speed with 100kmi on it.

He’s the second owner, was well taken care of, things pretty much mint except for some bubbleing down on teh bottom of the bed by the gascap and the edge of the tailgate.

been driving it for a week and a half now, he let me use it when my contour shit, runs absoloutely awesome and is 10x better on gas than my contour
