I am wondering if anyone can tell me what they think about the fact that I have replaced the serpentine belt tensioner and a water pump on my E with the mileage at 85,000. I just replaced the front brakes and had new plugs put in, also had the throttle body cleaned. I bought it used 3 years ago with 39 on it and other than a small pin hole in a radiator hose these are my first big problems. A total cost of almost 750.00 all together. If someone can let me know if this seems normal I would really appreciate it. Thanks!
