I think it's best to visualize what you want your car to look like and act like before throwing aftermarket pieces at it.

The JB4 is getting really good reviews on here for a piggyback tuner. I expect it will wake up your C400 quite a bit.
The AWE touring exhaust is another favorite for the W205 cars.
Do your homework if you want to go with 20'' wheels. This can be a PITA to get fitment right and some people have run into problems. 19'' wheels are easy since you can go with stock dimensions.
If you have airmatic on your c400 you can easily lower the car slightly with minimal effort. Lowering 8-10mm and adding 19's will give the car a sportier look without making major sacrifices on handling and comfort.

Thanks for reaching out darwin329.
I'm more serious about the computer upgrades at the moment. A nice set of wheels are are also on my list for this year but not imperative. I will keep you in mind.

Thank you Mr J!
I took a quick look at the JB4, it appears decent for the money regarding plug and play.
19's or 20's???... In the event that a great deal was to be had I'd do 20"s. I agree that 19"s are a more viable option, my preference. I'd like to go 10" wide but understand that the back spaceing is crucial. I want a nice tight un-aggressive appearance. Are you aware if the sock dimensions apply to a 10" wide rims?
I do not have airmatic but would love to lower the car 1". When I last called Pfaff regarding lowering springs there was nothing available for the c400. Any suggestions??
Thanks again gents I appreciate all the input available!
Cheers

I'm pretty sure stock dimension s for the 19" wheels are 8.5 front and 9.5 rear.
