I would definitely use the trailer because it may break down on the way home! I know many cars that had only a little salt water damage. The car was never the same again. No matter what you do or what you replace, you will be replacing electronic equipment forever. It is one headache after another and a lot of money just keeping up with it. I wouldn't put one part of this vehicle on my car (which is why I wouldn't take it even if it were for free).
