This is the second case I've heard of on the four cyl turbo engine putting a connecting rod through the block. The one I'm familiar with had approximately 53k miles on it. The owner took it to Mercedes and they replaced the engine at no charge. He also had unusual noises before losing the engine.

How many miles are on it? Personally, I would steer clear of the late models with the gasoline four cylinder turbo engine.
