This is the W204 C-Class saloon in C 250 CGI BlueEFFICIENCY form, built from April 2009 until the facelifted model took over in January 2011. Its 1,796 cc M 271 four-cylinder uses a turbocharger and direct petrol injection to make 204 PS at 5,500 rpm and 310 Nm from 2,000 to 4,300 rpm. Mercedes fitted a five-speed automatic as standard, and drive goes to the rear wheels. Mercedes quoted 0–100 km/h in 7.4 seconds and a top speed of 240 km/h.

It suits a buyer who wants a rear-drive Mercedes saloon with brisk performance and four-cylinder running costs. Mercedes' official combined figure was 7.2–7.9 L/100 km (about 12.7–13.9 km/L) on premium petrol, from a 59-litre tank; Nairobi traffic will use more. At this age, ask for the service history. Listen for a rattle in the first seconds after a cold start, because owners report timing-chain and camshaft-adjuster wear on this engine. Have a mechanic check that the five-speed automatic shifts smoothly.
