I have used Car Care Specialites for about 6 years and always have been very satisfied with their prices, service and advice. The owner, Larry Reynolds is very helpful and I believe is a concours winner. He has a series of articles on car care that are great:

I have no connection to this company except that I am a happy customer.

Here are a few other websites that I bookmarked and that I'll likely link to in the future:
