Follow-Up:
Apparently you think people who don't own one are willing a) to spend the time to find this site and b) to post a message documenting (in your opinion) phony problems. Why do I doubt this? Since you apparently are skilled enough to do "100%" of your own work, I'm not suprised that you don't share the majority view of these apparent pains in the ***. Unfortunately, most people that buy em aren't into spending their time working from "exhaust to engine to toilet."
