I would go for a 20 at least. World of diff, from my 16... The 114 engine is strong & to me tranny is smoother also.. 16 had waterpump probs. The 20 has been issue free for me . I may be wrong ,but it also seems to run cooler than the 16 did. Very happy with it. It's only $$ & ya can't take it with you. You earned ,,,now enjoy it. Best of luck,whatever you decide. Just come back & let us know .. We're a bunch of nosy guys..
