Bicycle rack needed

I'm wondering if someone doesn't have an unwanted bicycle rack lying around. It needs to fit a Yaris so it can be the version that attaches to the rear (see below) or the one that sits on top of a Thule roofrack (see below) as I already have a roofrack. The prices for these things are rediculous so I am hoping to get something secondhand at a reasonable price - or free ^^..^^..
