Yes, you still often see old carriages/cars used as farm structures when out and about, esp up in Buchan/East Aberdeenshire (closure of Inverurie depot?) - many are in very poor condition though and and not far from me, a house due to be demolished for a road/housing scheme was picked-back to reveal an old tram, which has gone for restoration:

I was friends with the grandson of one of their neighbours as a kid - and had heard the stories about the place being built from a tram but didn't really believe it till now!
