The canned lies that they use to manipulate customers are tactful yet transparent. The ethical issue is that they would not use these lies if they were not working. There are so many other options so it is best to avoid this place at all costs for any auto transaction including repairs. Skip them for warranty work too as they will do the work whether it needs to be done or not. So long as they can bill the manufacturer and make an easy buck, they are happy to steal. The pocket the money comes from matters not. Stealing is stealing and these guys lie and steal.
