2004 CLK 500 future Maintenance Cost and Mileage Life?
So far I had the car for over 4 years and it has been trouble free, but its not my DD either. I bought from 1st owner with full maintenance records and history.
Since I had it, replaced all fluids( PS, Coolant, Brake Fluid, ATF, Differential, engine oil), filter( including transmission), serpentine belt( as a precautionary measure) and air filter. For PS used a syringe to suck old and pour fresh fluid. Brakes have a lot of meat, rotors are good too. All pads/rotors were replaced around 65k. CPS(crank positin sensor) has been replaced by PO, as well as all spark plugs. Tires are good too.
All other hoses and suspensions components, fuel filter, radiator, mounts, I believe are 'Original'.
My question to you folks is, what else I would be needing to replace in near future? I do majority of stuff DIY. How much maintenance cost I should be looking at? Then I'll decide if I should keep or sell her?
Thanks for all of your inputs and help.
P.S: Transmission shifts very smooth and engine is quiet. Have dropped the pan for ATF, replaced filter, cleaned up everything well. Then again drained and refilled ATF after 5-6k miles.

On top of your maintenance, I did the following:
- Engine Mounts
- Transmission Mount
- AC Compressor
- Front and rear control arms
- Front and rear stabilizer bars
- All 4 shock absorbers + mounts (nothing was broken, I just wanted to refresh the suspension)
- Drive Belt Idler Pulley ($15)
- AC Footwell stepper motor ($75)
- Catalytic Converter ($230)
- Oil Cooler seals
- Valve Cover Gasket
- EGR Valve ($30)
- Coolant Reservoir ($37)
I live in Lebanon hence the prices. I wouldn't get rid of it if I were you given how reliable it's been. You may only need to replace suspension wear and tear items just like I did.
The M113 Engine and the 722.6 Transmission are bullet-proof!

Few follow up questions, please:
1- All engine and transmission mounts a DIY or can be a pain? Is there a DIY/youtube video for it?
2-Front lower control arms or upper and again, they are a DIY? Is there a DIY/youtube video for it?
3- Front stabilizer bar, an easy DIY?
How much was the price for these components, just a ballpark? I am sure, it'll be a bit cheaper here in the states.

2- For these, you need a special tool to remove some parts as my friend mechanic said so I doubt these are DIY for the whole job. Lower and upper arms are about $100 (US prices) so $400 for both sides at the front.
3- Yeah this one I would is a DIY. Front one was $100 and rear one was $90 (US prices).

Thanks again xserver
1- Mind asking which brand did you use and happy with it? Any symptoms of these mounts going bad?
2- Yeah, it might be that a press is need or a fork too or maybe something bigger?
3-Again which brand and happy with them? Any symptoms of them going bad?
So in a nutshell if I consider just front parts, then I be looking at ~$700 in parts and that's not bad at all!!!
Thank you

Very happy with them and no sign of wear yet. The difference when I changed them was huuuuge (yuuuuuge
)! The car got so much smoother.3- Original Mercedes parts and yes very happy with them. The squeaks were all gone and I could feel the ride got firmer. When I did all the suspension work, the car basically felt brand new again!

Few more things, you have never touched tie rod ends and any of the coolant hoses, yet?
Or any other sensors or alternator? Thanks

NEVERMIND, scratch the above. The tie rods were not replaced. It's the stabilizer links that were replaced in the rear. I mixed up the two.
No coolant hoses, no sensors, and no alternator replacement.

The Best of Mercedes & AMG
Thanks man, adding it to my action list
I perfer genuine MB parts.
In 2016, I replaced a driver side seatbelt, transmission cooling lines, low beam bulb, third brake light, hood support struts etc. Back in 2015, I replaced the driver side window switch, one trunk spring.

I appreciate input from xserver and mis3, at least I have a general idea in terms of the things it'll need and associated cost with it.
Think, I am going to keep the car for 1-2 years and when it'll become a money pit, then will think to get rid of her.

For instance, I was not at all discouraged while I had to replace the drIver side seat belt. This w209 is my daily commute and based on my rough calculation, at the minimum, this seat belt was used (extend and retract) for 40,000 times! Same for the driver side window switch assembly.
On the other hand, if the rear window switches fail (almost never used), I would be discouraged.
Recently I had to replace the 3rd brake light, I was impressed (also annoyed) with the 12 rivets holding the trunk lining. On a lesser car, there may be 6 rivets which actually would be suffice.

I still have a few days to think about it, but overall maintenance doesn't look terrible and am glad that I have done proper maintenance so far

BTW, mis3, have you ever had to replace the ATF electrical connector which goes into ATF pan?

By ATF electrical connector, did you mean the conductor plate?
Have you replaced anything on the suspension? Like tie rods, shocks, struts, ball joints or control arms or anything along those lines?
You are so right about the rock bottom, but I am glad that I bought it 'used' hence not losing too much. If you know what I am saying?
Thanks for all the help.
As for the othe suspension components, I am sure I replaced most of them in the past years. Last suspension components I replaced were the sway bars, front and back.
I bought my w209 new and it has been my daily driver ever since. I think I got my money worth!

BTW, so I assume you have changed it at least 2-3 times so far? Have you ever touched the conductor plate or no?
Honestly, that's what I feel in terms of worth of the money!
The conductor plate was replaced back in Jul-2013. The mileage of the car was 174K miles at the time.

Keeping my fingers crossed for conductor plate, hopefully have a long way to go!
When the conductor plate fails, you will know. Search for limp mode in this forum.

I'll order online and will replace it. So far no 'Limp mode' and hopefully never

Got it in terms of the conductor plate issues. Thanks again for all of your patience and help.
I am keeping the CLK based on all the 'math', thanks again guys.
