cycle rack for focus hatch

[hero of valour]

hi all
been a while since i posted as I've been cycling many miles...anyhow can anyone recommend a decent bike rack for a focus hatch 56 plate? i'd prefer one which went on a tow bar so i haven't got to clamp metal clips to my car! all suggestions welcome and thank you in advance!
