I may be wrong on this but I don't think it will work. With this set up you will have two pivot points working. If one starts to pivot the other one will not know what to do and you will have you car on the dolly ending up in the ditch. Rent a car trailer and be safe. The cost wil be a lot less than trying to fix the coupe if it goes into the ditch. If you can lock up the front wheels the dolly would work.
