“AAA arranged for Marks Auto Service to repair my 1999 Ford Van that broke down near Rockford. I was travelling and it had overheated, oil lost and lights were flashing and it started to smoke. They were very helpful and got it repaired and I have since traveled 900 miles and not a bit of a problem. Thank you.”
