The majority of cars on the road today are front wheel drive, and a number of them are flat towable. There are also all-wheel and four-wheel drive models that can be flat towed. It is determined by the internal design of lubrication for the transmission as to whether there are any modifications needed.
Suggesting that a dolly be used just becasue the vehicle is front wheel drive needs more consideration. A dolly is another form of a vehilce which needs attention to it's tires, brakes and in some cases license and insurance. And then there's where to fit it?
