Considering purchase of 2012 E350-4.
Considering purchase of a 2012 E350 4matic with 85K miles as an extra car. One owner (by a friend) and has been service by local dealer for all scheduled servicing and minor trim replacements and tires. I know the dealer for many years and the service director reviewed the past ROs (including the most recent B service last fall at 80K) and has no reservations about the car. I have read forums and it seems that the W212 is a reliable car but fairly expensive to maintain.
1. What are your views about repairs or servicing that will come up in the next year or two. I expect this car will be used for less than 5K miles a year. Does the factory scheduled maintenance require transmission fluid changes? This is new territory for me as my experience with E classes are with leases only with less than 40K miles in 3 years at turn in.
2. What do you think is a fair price (dealing with a friend). Steel gray with black/gray interior. Very good condition.
Thanks for any information your can share.

In comparison, I just took the wife's Nissan Murano to the dealer for 105k service, paid $600 to replace spark plugs, also did coolant change, brake flush, and trans service for a total bill over $1200. For a clean 2012 with a known good history, I'd peg the price around $15-18K, but I didn't look around at current offerings.
I've seen W212 E350 anywhere in the range of 8K to 20K depending on year and condition. 2014-2016 facelift models maybe more still.
Thanks

One thing that has surfaced from discussions with SAs at a few dealerships that might be expensive is motor mounts and engine mounts. I am hearing that it can run about $2K and fairly common with cars that hit 100k miles.
Anyone have views (or experience) with motor/engine mount replacements and are there other bigger ticket items that might go wrong.
Thanks

Service A - aka basic oil change = every 10K mi - costs $80 to DIY with OEM filter and Mobil 1 oil.
Service B - oil change with addition of air filter, cabin filter, brake fluid change , alternate with service A, so 20K mi intervals. I believe it's a bit overkill on the brake fluid change every 20K, filters are available at local auto parts stores or online.
70K mi - should have spark plugs changed and transmission service performed (replace fluid and filter in trans). My local MB specialist/performance shop quoted $500 for trans, $350 for spark plugs, that's about half of dealer prices.
Other than that, it's just a bunch of checks on the maintenance schedule.
Replace brakes and tires as necessary, or when the brake rotors are warped on E550 causing vibration, then replace them with Centric premium rotors yourself or any basic indy mechanic (see multiple threads on brakes). I've had to top off coolant a few times, bought a gallon of OEM blue stuff at the dealer for a gouging price of course, have only used a little of it because it full strength, so mix 50/50 with distilled water.

I very much appreciate all the feedback.
Finally test drove my friend's 2012 E350 4matic that I am considering buying. I met him at the dealership as he was getting a tire replaced (leaking) and I had a chance to drive he car (in the rain). It drove very smoothly and the condition is excellent. Only thing I noticed was a pulsation when stopping. Isolated to the brake pedal. No indication lights on the dash suggesting anything was wrong. I read through the history of repair orders and the fronts were done at 51K miles. Could not find any evidence on the RO report that the rear brakes were serviced with 85K on the odometer. Is that possible?
I checked with 2 NJ dealers for quotes on brakes (rotors and pads). Rears run between $650-750. Fronts run about $100 more. For giggles, I called Manhattan Mercedes. $1500 for rears; $1750 fronts. I guess they need to cover the high cost of Manhattan real estate although this is a factory store.
Have not really checked with indys but wondering what do you think the non dealer would charge. I also do not want rotors and pads that will not work as well as OEM. Not planning on wrenching myself.
I appreciate in advance your thoughts.

Dealers quotes for maintenance service are comparable, becouse they will include "free safety inspection" that will show you $$$$ in recommended jobs.
Bare in mind the price structure. You can buy used MB very, very cheap, becouse original owners don't want to deal with price gouging.
That leads to situation that few years old MB with lack of maintenance takes more money to bring it back to standards than the purchase price was.
If you don't DIY, you will be for constant shocks.
The money you save in parts and labor for DIY and independent shops could probably be more than you think.
