I was looking for a hitch for my EB Mustang so that I can carry an e-bike (they're heavy, so a trunk rack won't hack it - has to be a hitch mount). I came across the Stealth Hitch and I think it's an awesome design - completely invisible when not in use! They are made in the USA (Yay!) and seem to cater right now to higher class brands: MB, Audi, BMW, Porsche, etc.
I submitted a request for them to consider making one for the Mustang and actually got a reply from the CEO, Steve Nance. He said they are starting on Ford models this summer, but so far there hasn't been much of a demand for the Mustang. If you are in the market for a hitch for whatever purpose, please go to stealthhitches.com and in the Shop Hitches section select the Let Us Know! link to request a Stealth hitch for the Mustang. I really don't like the way the Curt and Draw-Tite models are visible below the rear bumper.
