I just bought a 2007 MB C230 first week of May 07, after 2 weeks, traded in the car for a Civic Hybrid with navi system. Had to learn a whole new driving method, enabling me to average 45-55mpg highway and city mixed driving. The interior feels well made and thought out. The lay out of the control panel is user friendly. I test drove the Prius and compared it with the Civic hybrid; the Civic has more accessible lay out. The Prius felt like an office desk on wheels. Was able to upgrade the interior with leather... the shiny Silver leather made the interior 200% more attractive!!! The handling of this car was better than my recent MB C230. Audio is great, with aux input for mp3 players.
Everything. Interiors are fantastic, gas milage is excellent.
Moonroof and bluetooth options, more cargo space, more compartments/storage in dash.
