that's the problem with warranties so unless you DIY it will cost you ( you have to let go of the apron strings one day ) otherwise you will pay through the nose, are they worth it now that's the question would I buy one and that's simple NO but im a mechanic so easy for me to say that but when you have sites like this you learn to DIY because that's what these sites are all about

 

My car was Audi certified - warranty is through them.
