1984-1986 monte carlo ss?

Im looking to sell my 86 caprice, and i was thinking of buying a 84-86 monte ss, my problem is that i know near nothing about them, are the engines different in the 84-86 montes? is one better than the other? i live in florida, so cold starts wont be an issue really, but im 19 and want an older car, but i don't want constant money absorbing car problems, what year between 84-86 of the monte ss is the better car to buy? ohh and do any of those years drive faster than the others, because i would like the faster of the cars, please share all and any advice or insight on these cars, i cannot find much about them online, thank you
