Not sure the exact nature of the question, but yes you can tow a Chevy Sonic on a dolly, some models can be towed 4 down. If youโre concerned about weights, the combo of a dolly and sonic (unless loaded with rocks) should be well below your max tow numbers.
I had a 2013 Sonic w/automatic and towed it 4 down. Good car. Newer ones have more electronics and such so consult your manual on the exact procedures required to tow it.
