Thank you all for your excellent responses. They were a great confidence booster and i think i will tackle this. The reference material suggestions were great too. Wayne, I agree with your analasys of the shop expenses and yes corvette owners are difficult to please. However I,m a guy that likes to do as much as I can whenever I fell I have the know how to do something right and I am very hard to please. It has been my experience when dealing with someone who has performed unsatisfactoraly and complaints are made the consumer is usually the bad guy. Most people today in any service business seem to forget the art of customer satisfaction so they can have a repeat customer. I"m a field service engineer and beleive me I know how customers can be. Hope this doesn't offend you as I certainly don't mean to. Thanks again all you for your help and look forward to more help as I undertake this project
