I also did the tow-bar approach, but also found the turning radius of the Midget - whish has been choked off considerably, wound up giving me some issues with the front end.
In 2013, we used a tow strap, but found we were wiping salt off of the front of the car every time we came from a run, whereas the tow bar DID keep the salt from kicking up onto the front of the car.
While I tow with an open trailer, I still find the lowness of the car requires me to raise the tongue in order to clear the exhaust onto the bed where it breaks over the ramps.
I'm thinking of devising some sort of a pivoting dolly that can be tucked under the car for transport - probably with 8" or 10" light-duty tires. The car only ways ~ 1600 lbs, so I can cheap out on that aspect a bit.
