Research for this car

Generation guide Mercedes C-Class W203 (2000-2007): known problems and buying guide
A middling buy. Check the timing chain, gearbox cooler and body first, and expect rust on cars built before the 2004 facelift.

Start the car cold and listen for a metal rattle. Ask for proof that the chain, tensioner and cam sprockets were replaced together. A scanner reads camshaft codes. Bad result: a rattle, a check-engine light or no record.
On a lift, check the wheel arches, sills, lower door edges, boot lid and tailgate. Bad result: bubbling paint, holes or fresh filler.
Check the boot for damp under the trim, and the sunroof drains. Test the rear and brake lights. Bad result: damp under the trim or a rear light that does not work.
Turn the key through all positions and start the engine. Ask whether the ignition unit was replaced and coded, and how many keys work. Bad result: a stuck key or a starter that does not respond.
On a lift, check ball joints, control arm bushes and tie rods for play. Bad result: knocks over bumps or uneven tyre wear.
Look for oil at the camshaft adjuster magnet valve and ask whether an oil-stop cable was fitted. Bad result: oil on the plug or wiring.
