I'm curious about people's opinions on car wax. Some people think it's not necessary with a clear coat. Just keep the car clean. While other's obviously live or die by the waxes they put on their car. Perhaps it's not necessary on new cars. But wouldn't a wax extend the life of said clear coat? If so, what's the best wax?

I've love to keep my 6 month old Z4 looking fine for many a year.
