I just acquired a 2004 C320 Wagon with 170k miles. The PO said that the car needs to have the valve body replaced as the car goes in to ‘limp home mode’ after driving 20+ miles. Where is a good place to get a used body? I’ve seen a few on EBay but wonder who you guys recommend. Also do I need to get a specific one or will any for a W203 722.6 trans work.
