Yes.
When I drove a Peugeot 309, I mounted it crossways on a towbar mounted rack. The kind that has two prongs sticking out to hang a bike from its top tube. Bungy to secure the front pedals at 12 and 6 o'clock, to minimise the length/width. Beware lamp posts when reversing out of your friends' driveway.
I then graduated to a roof mounted rack. The one from, umm, Pendle, which has been fixed to a succession of roofbars as I've changed cars over the years. Drilled some extra holes in the rack so I could move the front wheel channel to accommodate the shorter wheel base and moved one of the uprights for the same reason. Wobbles in what looks like an alarming manner, but nothing ever fell off.
