Could be interested in a new 80s, but which one?

Hi guys, here some people have said: If you should buy an 80’s, it should be a 5cylinder. Yes? Now only which one? Can be that I then get one, and by the way my old one. And then sell it. Which do you mean then? B3 B4? 116 or 133, 137 or no idea how much horsepower? have already one in view. But is a b3 with 116 hp. MFG Dom
