I had one for my C4. Made a big difference in interior temp after parking at work during the summer here in Dallas.:thumbsup:Has anyone tried the fabric top from Mid America that you can use while the car is parked? They say it weighs about 5 pounds, and can be installed in seconds. It is on page 107 of their newest catalog. Even if it is ugly it might be a way to keep the targa top stowed and use the fabric while parked.
