2005 Mercedes-Benz C320 Reviews

At 48000 miles an oil leak showed up on the right side of the engine. At 58000 miles this message showed up "engine oil sensor malfunction, go to workshop". $611 to fix and was not given any reason why it broke. Inside passenger side grab handle just broke, very cheap workmanship. Be careful when you park because front spoiler will be damaged by a parking lot's wheel stopper. Very low front.
