Thanks. Yeah, it bothered me too! I called the other shop "Benz Haus", that I KNOW has been in business for many years and has a good reputation. I spoke to the secretary initially and she said the guides were only about $3.00 each. She said the labor on changing the rails was much more expensive to replace. I did not know that extra cost or work about the upper rails. I was thinking it was going to be only a minimal increase in the price, obviously a lot more work is involved.

I wanted to know the cost of replacement on that and she transferred me to one of the mechanics. He said he has been working on these cars for 15 years. He said personally that unless it was making a noise then he would not change the chain or the tensioner @ this time. He said I should still try to obtain some of some service records from the original owner, but obviously I do not even know who that is.

I told him I was unsure about the rails or guides. He said it was not as much as a concern as the chain/tensioner. He said if it broke, it was not as high of a chance of engine damage, as if it was the chain/tensioner. He said if the chain or tensioner broke, then it was severe engine damage, which I knew.

I know there is a possibility that I may be sorry down the road if I do not change it right away.
