x166 cost of repairs

If you are buying this car you should definitely do a pre purchase inspection,i thought i got a good deal on my car but it actually needed a lot of work,some things you can do yourself such as press in new bushings,spark plugs,filters change etc.
it has 119k miles,it drove great when i bought it and it still does
so in last 7500 miles i have replaced:

-rear airbags-200$ oem bags from ebay and 200$ labor to install(car would go all the way down overnight)
-radiator-800$
-turbo coolant return lines 1400$(it would leak lot less in cold weather)
-new tires-found a good deal on toyos on walmart website 275/50/20 installed 550$
-air intake hose 50$
-now need to do front brakes 900$
-motor mounts 1200$
-diff mount 250$
-front lower control arm bushings 750$(ill try this myself)
-brake fluid flush 200$
front cv boots 550$
​​​​-force matched wheels and tires(common cause for vibration at 75mph)350$


im hoping once i fix all this and flush diff and transmission fluid car will be good for another 50k miles

Most of the list is a diy except motor mounts. I wouldn't pay 900 for brake job.

Brembo or not 900 is still a rip off. Once anyone hear Mercedes - they expect to dig in your deep pockets.

DIY is the way to go on brakes. They are very easy to change on the X166. My rotors were stuck on the hub so those took a bit of work to get off. In the end, spent $400 for new pads and rotors on my GL63.

These are the ones I'm running on my GL63. They will not fit a GL450.

They were $400 shipped when I purchased for front and rear pads and rotors. Amazon and Ebay seem to be out of these for now. Either way, I can pieces a similar setup for my 63 for around around $600 but it can be done cheaper for a 550 or 450.

Here is a set for the 450.

to add some numbers here

I can also add some examples of typical maintenance items a dealer in the Denver area recently quoted me on.
For most I respectfully declined for unjustifiable high charges and easy DIY (all are without taxes and shop fees):

- CEL on diagnosis: $185
- Airmatic software update: $56
- Xentry compression test: $93
- Oil and filter change: $208
- Engine air filter: $325
- Brake fluid exchange: $222
- Transmission fluid and filter change: $1,076
- Spark plugs: $975
- Wiper blades front/rear: $151
- Serpentine belt: $370
- Replace transmission cooler and transmission lines: $ 4,867
