wise words overseer!
A very valid point, you should never give away cash needlessly to a dealership when a specialist will do, but they do have their uses! If you go in there and tell them exactly what you want them to do and look like you know what you're talking about, then you won't get stung!
I have the advantage of experience in being a service advisor for VAG. Luckily, the company i worked for were very honest, but you do get others that will get your car in for minor work i.e. oil change, and 2 mins later, the service advisor is coming over with a list as long as his pinochio looking nose.......brakes, suspension, tyres, etc.etc. But you can say NO.
The thing is, that when a franchise dealership gets a car in for service, they like to look over a car and tell you exactly what the condition of the car is. The reason for this is that, if a car leaves the premises in an unsafe state, there is an element of comeback involved.e.g. if you take your car in for an oil change, and they fail to tell you that you have bald front tyres and you then have a crash, you could argue that it was the dealership's responsibility to tell you!
