I like the CoCo mats.I use Continental Motors in Sunnyvale. I have a 84 spider and it requires a star smog. I have Richard at Continental get it smog. I always get a thing or two done at that time too. The running joke is Richard always says to me when I leave the shop - see you in two years. But my car does run great. It is far from being a car show winner but it runs and looks great and I have a lot of fun driving it.
