Is it possible to fit a 16" wiper to the back of a C240 estate?

What year? Most auto stores/places will let you take a wiper out to the car and mock test fit it to see if it'll fit...but if 15.5 barly has clearance then you probably should be using a 15inch wiper...there should be 1 inch - 1 1/2 clearance from the edges, when the wiper makes the sweep....you can varify this also at the auto store have them look it up and see what is the correct fit/size

(to give an accurate response a model year is needed...it is possible to fit the 16 inch if you don't mind it wearing out on the end, and possibly having the metal edge scrap the glass)
