Read the Honest John Review

Mercedes-Benz CLS (2011 - 2018)
Big CO2 reductions. Four-cylinder CLS 250 CDI available at last. Precisely-built interior. Retains unique style of original CLS. Comes with full LED headlights.
Mercedes-Benz CLS (2005 - 2011)
Dramatically different from any other Mercedes, wonderful styling, great engines and transmissions, incredibly refined with a forgiving ride.
