Make sure they are not doing something daft on the window issue like having left the window lock switch on (located drivers side door arm) - but otherwise yes I have heard of some zeds suffering from dodgy passenger side windows.
Its not temper orange btw
Otherwise 'looks' in good nick - but clearly drive more than one car, so you at least know if it drives well. If you look on the site you can see lots of posts of people who have much better behaving gear boxes than others, better engine drive/power etc - if you take the first one you see, you wont know if its a good or a bad one - bodywork is nice to have but its got to be mechanically good too and you wont know unless you check a few out.
