The last car I treated like that was my red, 92 Mercury Capri rag top turbo. Every weekend, wash, dry, and wax. I loved doing it. Kind of a Zen thing. I lived in Napa Valley then, and it looked good for the whole week. Now I'm on a gravel road in Vt., with a black car. It won't look good for long. I got the XF just a couple weeks before the snow, and only washed it once B4 it's long winter nap. This winter is getting OLD!
