Way too much money. My experience is almost totally technical but even I know that is too much money. Besides the mileage has no significance without service records for verification.
The average car is expected to look original at ten years on a MB. It takes a keen eye to pick a well cared for 200K car from a claimed 70k car. Witness the recent posts from a gentleman who thought he had a valuable clean car with 175k miles.
