Credov's researched list of the 4 faults the Mercedes-Benz E63 is known for (2010–2011), 4 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: On a cold start listen for misfire or rough running, and look in the coolant tank for oily scum or bubbles.
Why it matters: A snapped head bolt can end in coolant loss, overheating, a hydro-locked cylinder or a ruined engine, and the fix on many cars means taking the cylinder heads off.

What to look for: Insist on a cold start after the car has sat overnight, and listen at the front of the engine for rattle.
Why it matters: A stretched timing chain upsets cam timing and can jump a tooth; Mercedes issued a documented fix (non-return valves and new tensioners) but not every car received it.
What to look for: Check the rear sits level with the front and not lower on one side, and listen for a long-running compressor.
Why it matters: A leak overworks and eventually burns out the compressor, turning a cheaper air-spring repair into a much larger bill.
