Well I just recently purchased an 04 wagon. Yesterday was the first day I go an oil change and the first time i have seen underneath my car. To my surprise most of the bottom of the car was the color of rust and dirt and had rust all over the piping. The pervious owner said he had been to Baja once and goes to Tahoe once in a while. Well he wasn't very knowledgable about the vehicle but seemed like he took care of it. I don't think he knew to get the car washed immediatly after returning from the snow because the salt that they lay on the roads up there is canceries to your car. My question is if there is any place I could take my car to have the under part of it steem treated or cleaned up and how much it would cost. it bothers me that it looks like rust under neath my car. Thanks in advance for all help.
