w203 C240 Mods???
ECU Tune I like eurocharged thats what I have had now for over 50,000 miles. for a c240 it claims 17HP and 15lb-ft but for a c240 I feel like the price is way to high for the gains IMO.
I would assume that exhaust would be something more fun so at least it sounds cool. Besides that though not much to do besides upgrades suspension AMG front and rear bars or other upgraded bars will transform the car add on new springs and sport shocks and it will be much more fun in the bends. I have amg bars as I don't autocross or anything and want to have some comfort still. Then I have Tein springs but would recommend another brand as they are cheap and probably not the best. I have renntech front shocks and Koni rears and love the setup but will get koni shocks once the front wears out. I got my c320 when I was 16/17 and slowly did things to make it more fun. I did everything above but also got a set of BIX, OEM nav unit, Clear mirror turn signals, 05 sport rims for summer and originals have snow tires on them now. Wow when I look at all that now I know where all my money went over the years oh and gas... car has 213k miles on it now lol

I would guess 5k minimum for a turbo/supercharger setup but would not be surprised if that quickly turned into 10. Engine swaps are also very expensive on Mercedes for obvious reasons.
