The entire service can be done anywhere as long as it is done correctly and completely. Correctly means using correct types of parts and fluids (approved by MB) and completely means taking necessary corrective actions indicated by proper inspections.
You can, for example, change your own oil and filter and conduct your own inspections, but you must keep a maintenance log (date, time, mileage, receipts for parts and fluids AND document in your log all aspects of each “Service A” and “Service B” including conducting required inspections and corrective actions taken if any).
Yes, the vehicle has monitoring systems and warning devices, but the inspections are intended to verify the monitoring and warning systems are not missing anything i.e. not working. Kind of like checking tire pressure with a gauge once in awhile, etc.
If you go to the stealership for all recommended maintenance, the warranty coverage is kept in tact most assuredly without further question regarding proper maintenance. If you do it yourself, have someone else do it, or use a combination of these methods you better have good records should a warranty claim be necessary.
A few bucks can be saved going to well qualified independent shops, but not worth it to me while warranty still applies.
A lot of money can be saved going to the “local wrench turner” or even more by doing it yourself, but keep meticulous records demonstrating ALL items including inspections were completed including corrective actions taken and receipts for everything showing proper parts and fluids were used.
One last note... anyone can make a mistake. If your stealership screws up you get taken care of... what if your local Quick Oil Change place makes that same mistake? You’re out of luck! I know it’s rare, but it has happened where oil is not replenished after draining the old oil, for example.
For my peace of mind, the welfare of my vehicle and those that drive it, and the security of an intact warranty without the spotlight being turned on me for proof of correct maintenance, I choose the stealership for maintenance. YES, THE PRICES ARE TOO HIGH, but I guess the same could be said about what I paid to buy the darn thing (which I have heard to no end from some people).
It comes down to personal choice just like which car you bought, whether or not you buy extended warranty coverage or prepaid maintenance, and how you drive. There are pros and cons to all of it, so gain as much knowledge as you can to understand the various advantages and disadvantages then make a choice you can live with regardless of what happens beyond your control.
Theories abound about how cars are treated based on vehicle history. I have owned all kinds of used and it’s a crapshoot. Some one owner cars are babied, and some are driven hard by the same one owner the whole time. Some one owner cars are well maintained, and some never have the oil changed.
You don’t want frame or flood damage and you won’t get that in a CPO.
Do you’re due diligence as you would any other used car and go for it if it checks out.
Good luck!




So when you get to 8,000 miles, start waiting for your dealer to run a special and when he does do your service. If you have to wait to 11,000 miles no damage will be done nor will your warranty be voided.
That should give you enough leeway to schedule your service when your dealer has a special.

Make the best deal you can now, enjoy your new Mereceds and stop worrying about what it may or may not cost you in three years!

One other thing too, things like spark plugs and transmission fluid aren't included in Service B, it's usually an additional charge by the dealership. But it's included in the maintenance package and they let you buy it up to 80k so it's a decent deal if you hit it at the 50/60/70/80k marks where plugs, fluids might be needed.

If you're doing a lease, it's a crazy good deal because if it's 2k, it gets rolled into the purchase price and if the residual is 50%, then you only end up paying 1k for it on the lease and in theory at the end of the lease, the PPM has a 1k value when it reality it doesn't. Crazy math.
There's not much of a discount on them, you can check the extended warranty subforum for various vendors that sell them. But what seems to be common now is that the dealers mark them up over list price so it's still a decent deal if you buy them from the vendors mentioned in the subforum.
MB CPO Ext LTD Warranty: $3899 dropped down to $2588
MB PPM: $2830 dropped down to $2000
MB Tire and Wheel Plus: $2599
Appearance/Windshield Protection: $1798
Theft Protection: $719
Dent Protection: $899
These are just some numbers for MB in the Bay Area. Ended up paying around $48k for the final price for the car with PPM.
