If you lived in a snow/salt area, the picture wouldn't be that pretty! I was just looking at mine after the 45,000 mile oil change and it is not that nice.
I thought the operative word was "TRUCK". If it gets dirty, so what. Snow, ice and salt, fact of life for many. I do however, clean under my truck, yup! And use an "undercarriage" spray to keep it looking nice. Its not as nice as yours, but it will do for me. Bob C.
