Did you know that this car has a built in smog sensor? I didn't and I'm a fiend for European cars. It constantly monitors air quality. When excessive pollutants are detected it automatically shuts off incoming air and recirculates filtered cabin air for 20 minutes. Pretty nifty. When the vehicle is off it won't allow the doors to lock with the key in the ignition. Just two of the way too many to list features on this luxury sedan., , Know how much this car cost in 1999? Pushing $50,000 - with good reason. The E series is a flagship for Mercedes - great motor and glowing, 5 out of 5 star owner reviews all over the internet. This is an opportunity to experience European engineering for yourself. Just be warned. It's positively addictive. , , This car appears to have been very well mechanically maintained. Runs and drives like a dream.
