From 6 video reviews and 1 press test · updated 24/09/2026

What the reviews say

• The 2001 W203 C320's 3.2-litre V6 and five-speed automatic deliver lively performance, a comfortable ride and agility, though the steering felt heavy and short on feedback.[5]one sourceW203
• In a long-term test, the 2008 C320 CDI impressed with strong, refined performance and quiet, relaxed cruising; nothing failed over 9,513 miles and six months.[7]one source
• The 2007 C320 CDI suits faster roads: the source praises its comfort and stability, but it is not especially agile through slow bends, while the diesel adds noise and vibration.[1]one source
• The 2003 W203 C320 has a well-finished, generously equipped cabin, but the rear is comfortable for two; a third passenger is cramped.[2]one sourceW203

Typical faults

• The W203 body is highly susceptible to corrosion. The inspected car had rust in the doors, lower wings and above the windscreen; at least one door already required replacement.[4]one sourceW203

  2000–2007

• The inspected 2002 W203 with the M112 3.2 V6 had intermittent misfires; after plugs and coils were changed, testing identified two faulty ignition leads.[4]one sourceW203

  2002–2002 · M112 3.2 V6

• The same 2002 M112 3.2 V6 showed markedly low compression in one cylinder. The source suggested valves or rings as possibilities, but the precise cause was not established.[4]one sourceW203

Which engine and version to take

• For the W203, consider the M112 3.2 V6: one source calls it reliable, while a 2002 example in another video remained lively at 640,000 km. That does not guarantee another car's condition.[4][3]W203
• The 2008 3.0-litre C320 CDI is a strong long-distance choice: its smooth torque impressed in a long-term test, with no failures recorded over six months.[7]one source

What to check at the inspection

• On a W203, closely inspect the door bottoms, wings, area above the windscreen and underside. Look for rust, filler, uneven paint depth and poor-quality repainting.[4]one sourceW203
• Test the M112 3.2 V6 both cold and warm for vibration or misfires. Check the ignition leads and compression rather than relying solely on fault-code diagnostics.[4]one sourceW203
• During the test drive, check automatic shifts and D/R engagement, and listen to the rear suspension over bumps; the inspected car showed a jolt and a dull knock.[4]one sourceW203
• Request complete service history and verify the work performed. In the source, a well-kept 2001 C320 was backed by extensive service records and regular oil changes.[6]one sourceW203
• Test all cabin electrics: seat and steering adjustments, sunroof, climate control and parking sensors. The 2003 C320 has many powered features, while workshop repairs can be costly.[2]one sourceW203
