I was wondering if these products are worth the money?  We have a 2008 Trailblazer, a 2001 Silverado and will be purchasing a newer sedan for our daughter also.  I am wondering about your experiances both good and bad.  I have never used these before and both vehicles are running well, and I know sometimes you don't want to mess with a good thing.  Just wondering.
Thanks Gang,
Cal
