Bit of a strange question I know, but on the Stilo it's on the left side as you stand at the back of the car, and is like this in italy. However, the marea's and punto mk2.5 are on the right side in the UK. Looking around, there seems to be no sensibile pattern.

So which side should it be on, or doesn't it matter at all??

Thanks

It shouldnt really matter, as some cars have them sweeping from the side and down (rover 45, Last gen Civic) for the rear wipers.
Just by looking out the window, most cars have it on the left, while a clio has it on the right

thank god for that, i will sleep tonight at last
