flat towing - whos done it? pros and cons

Years ago my buddy and I towed my old '69 340 Swinger behind his '64 El Camino to go racing at OCIR.
I had some tow tabs made that exited under the front bumper and he had a custom tow bar made at his work.
We never experienced any problems.

Today, I'd rent a car trailer.
Like this? We used this to flat tow a 440 Duster to riverside, in the eighties.
