Looks like normal to me. You just need to catch up on any missed maintenance. Valve adjustment, fuel filters, injectors, coolant flush etc.

Thats the problem with the W115, its very difficult to know if it has 0xxK miles, 1xxK miles, 2xxK miles, 3xxK miles etc. A good car might look like it has, for example, 160k miles but in reality it more likely has 260k miles.
