I am spending 4200 on my E250 to replace some worn front suspension components, change transmission fluid / filter and drain refill the coolant and replace the serpentine belt and associated pulleys. The car has been great and the few repairs over the years have been covered under CPO warranty years back. I change the oil and filter, as well as the engine,fuel and cabin filter ( I buy these from FCP Euro and get most of my money back returning to FCP under their warranty). I just moved so my garage is full of boxes or I would have changed the trans fluid myself as I have in the past. Dealer quoted 1150.00 for trans service, Indy is 783.00. The front drivers seat has slight separation at the seam but over all the car still looks almost new. I think staying on or ahead of oil changes and filters this car will run 250,000 miles or more. I bought the car from Benz dealer for 24K CPO and still under factory warranty during VW diesel gate. Also got a check for almost 3K from the lawsuit. I keep a scan gauge plugged in so I always get a complete regen burn. I run Liqui Moly or Motul oil. I am on my second set of Drive guard tires. I had a flat at Mount Vernon ( George Washington’s Home ) the run flat did it’s job and got me 40 miles back to a tire shop where I had a regular tire installed to drive the 600 miles home. Road hazard paid for half on my new run flat. The dealer replaced the DEF heater and fixed a slight oil seep under warranty. Car Had the emissions update a few years ago.Local tire shop did brakes all the way around a few months ago. I flush the brake fluid every few years.

Posting this for anyone wondering how things go as the miles increase. Only items Indy said to monitor was the motor transmission mounts and the flex plate.

 

Mine, the same MY with 150k miles needed sway bar links boots and Motor Mounts.
AEM gave it most of exhaust system new, so should last.
