2009 Mercedes-Benz S-Class S550 4MATIC 4dr Sedan AWD (5.5L 8cyl 7A)

Review

Generally I loved to drive this car. Reasonable performance for a full-size sedan. However, it's exceedingly thirsty. As always, the published fuel economy is way more optimistic than real world driving condition. A typical mix of city and highway gets about 450km out of a 100l tank. Do the math -- consumption is generally high teens per 100km. After just over 4 years of age, and about 52000 kilometers, the transmission failed. The cost of parts and labour to replace the entire transmission was over $14,000. So where's the "legendary reliability, to quote Mercedes? It's a legend!

Favorite Features

Sirius satelitte radio. Keyless go. 4Matic system.

Suggested Improvements

Reliability is tragic -- needs improvement. Bluetooth is way too slow. And system can't load large address books. Gives up after a couple hundred entries.
