Comparison massey 1135 to 1155

[massey1100]

Hi all,
I'm a new member, but long-time farmer. I am looking to buy a new-to-me tractor for my farm. I have my mind set on a Massey Ferguson and am interested in either a mid-70's 1135 or 1155. I was hoping someone out there had some insight outside the specs I have been able to read on the net. longevity, maintenance, fuel mileage etc.?

all i can say is the 1155 aren't very good on fuel but have lots of power and are a pretty decent tractor
