Buying c32
Other things to look out for are rusty wheel arches,common with w203's. Stepper motor,noisy SCbearings plus many more.
These are great cars and can be pushed to over 400hp for reasonable money,but can be high maintenance.
I just bought one a few months back. Get a glycol test to begin with. If the glycol level is safe (<1%) the radiator is fine. However if it is the original valeo maybe get it replaced for piece of mind. I'm about to do mine to be on the safe side.
Other things I'd check:
Transmission jerk @ 1500rpm ... manifests itself when driving slowly in traffic. Put the gearbox in 'w' and accelerate gently up an incline. If you feel a thump at 1500rpm it has the problem. Feels like a rough gearshift but it's not shifting gear. Cheap fix, replace the tcc/pwm solenoid ($60parts - about 2 hours labout) and transmission flush (coolant cost).
Check your pulleys for noise (raspy, grinding, rattling, wobbling). Common things to look for here are:
supercharger pulley
groved and smooth idler
tensioner pulley
Check the tensioner has not worn out and is still applying correct tension on the s-belt. Should only wobble a little bit.
Check the supercharger clutch
intercooler pump often dies on these. It will cause the sc to cut off due to high intake temps. replacement is ~$150 + 45minutes diy
intercooler leak - you'll notice coolant being lost and get low coolant errors. Hard to detect before buying, you need to pull off the intake manifold covers and check for residue. big $$$ to replace
apart from that general checks you do with any car ... shocks, tyres, bushes oil leaks etc.
All in all the motor and transmission on these seem bullet proof. It's maintaining all the 'other' stuff hanging off them that can be a pain.
Anyone else got any ideas?

As you guys can see im a newb on the forum BUT have been watching and learning for some years now untill i get my own benz. Finally was able to afford a c32. now i would really appreciate a little help. The Motor is very quite and no funny noises from the engine side.
1. How do i know my supercharger is actually working? what will give the indication? the whine on mine is barely audible or non existent, the car had some major work done on it with regards to seals and belts etc before i bought it. ( i Suppose the fact that i can hit 210 within like 12 seconds a good enough indication?)
2. I dont have the transmission jerk at 1500rpm, but sometime if im driving slowly (like most of the time) maybe 60km\h it feels as if the gears change up too quickly and when in the higher gear i press gas pedal to maybe 50% i get this HUH HUH HUH sensation till the revs climb and then she rockets forward. Like the transmission is confused or something. Could there be something wrong with my gearbox? I have tried the TCU reset that is on this forum also but dunno if it worked or not as there is no indication if it really did reset. This might be happening in third gear i think. I also noticed that happens more so when the car is nice and hot. Sometimes i also think that this has something to do with the charger? maybe not engaging till a certain point or something?
3.To the south african forum users. Did anybody see or hear about a c32 with plates SEELEN ZN. id like to get in touch with someone if possible to get some history on the car.
Apart from the usual small electronic quirks etc i am absolutely smitten with the car.
Any help from the gurus will be highly appreciated.
Thanks
