Likely a bad ignition tumbler, considering the key "sticking" in the start position.

Best bet is to hit the dealer and ask one of their service advisors if they've run into this problem before.

SOURCE: Ballpark price on 2007 Mercedes Benz C230 Maintenance B

The dealer near me charges $365 for a 4-cyl, $395 for a 6/8 cyl, or $425 for a 12-cyl. The only actual repair/maintenance you get for that price is an oil change (with Mobil1 and the MB filter, which are CRITICAL, ~$120 on its own) and tire rotation. This makes a lot of people think it's a scam, but really, it's a little steep, but definitely worth doing. The rest of the service consists of a massive inspection of your vehicle covering the following items.

-- Fluid levels
-- Tire tread/pressure/wheel condition
-- Air filter (inc. clean out housing)
-- Cabin air filter (inc. clean out housing)
-- Lubricate sunroof rails, locks, hinges, and seals on body.
-- Drive belt and tensioner
-- HVAC system operation
-- Instruments, cruise control
-- Wipers/washers/lights/horn
-- Windows/sunroof operation
-- Hoses
-- Transmission fluid
-- Brakes
-- Chassis/suspension
-- Driveshaft, inc. flex discs
-- Road test
-- Reset maintenance light

This is actually pretty essential to do, despite seeming like a lot of money for not much work. I have very rarely done one without catching a few things that the customer needs, and often it was a problem that would have gotten far worse had it been left to its own.

SOURCE: Mercedes c230 windshield wiper starts on its own

Car has rain sensing windshield.Most likely you have the wiper on/off level in the intermittent position,which turns on the sensor. When the sensor detects moisture or even dust sometimes. It turns on wipers. Just make sure the wipers are off and not in the intermittent position.

SOURCE: C230 Key Won`t Turn the car only went i use 14.3V

The starter is turning only when the solenoid close the contact to deliver the current to the starter . When this happens it then turns the bendix to engage with the flying wheel to start the engine.
The reason that you need higher voltage to have correct needed current going through the contact of the solenoid, hence the starter. The contact is corroded or rusty due to high spark at high current at every start time causing high resistance. V=IR the R resistance of the contact now is high so it need higher voltage (14.3 vs, 12.8 V) to deliver the same needed current for the starter.
Unfortunately, the solenoid is integrated with the starter, so you can not just replace the solenoid without replacing the starter.
If you can find the new battery holding at 14.3 V as you mentioned, then that is an economical solution since replacing the starter is costing more.
BTW where can I find the battery at 14.3V in case my friend's car has a same problem?
