Hypothetical scenario, you just got a 50k miles 2013 PPP C63, what do you do?
Vehicle has been maintained at Mercedes throughout its life and is completely stock.
Injectors? Transmission service?
- Engine oil and oil filter replacement
- Air filter replacement
- Spark plug replacement
- Transmission fluid and filter replacement
- Rear axle fluid replacement
- Brake fluid flush
- Power steering fluid flush
After this I'd look at rotor and pad condition and replacement if necessary and definitely new tyres if the existing ones are shot because quality tyres is a must on these cars. The above should be done before any performance mods are considered if you want a reliable performance car for many years into the future.




Injectors might be a good idea, I did mine after 5 or 6 years as they tend to have issues with leaking. Belts and pulleys might be good to do, pulleys tend to get noisy after a while, mine where a bit rough after 6 years so I changed them.
Inspect your engine mounts for leaks and valve covers tend to leak also so good to inspect, otherwise cams, lifters and cam adjusters are good to inspect if you get any ticking or tapping noises from the valve train.

After that: wheels, aero parts and go fast mods too if you're into that
AND ENJOY da powa!




Maintenance and points as said above, then get out and enjoy the vehicle
So no modifications that are game changers? I am not just talking about power as when I first got a BMW, the list of mods to improve the handling was long!

Engine oil and oil filter replacement - Definitely.
Air filter check - should have been replaced recently.
Spark plug replacement - need to check detailed SH to see when they were changed.
Transmission fluid and filter replacement - Definitely
Rear axle fluid replacement - Definitely
Brake fluid flush - Definitely
Power steering fluid flush - Definitely
I will replace injectors before 60k as I have read quite a few people have done this and noticed an improvement. I also don't want any risk of hydrolocking.
