The new dash redesign inspired by the E-Class was a big improvement over the old design. The ext. and into fit and finish is flawless. Although it's a four-cylinder, it has great acceleration because the car is so light. The ride is firm, smooth and quiet. The opt. leather seats are firm and comfortable but lack a full range of adjustment for the front seat bottoms. My seats also have suede, which feels much better than leather in the Texas summer heat. The gas mileage is great. Seven-speed trans shifts smoothly. Nav system works well. Blind spot warning feature is excellent. The keyless go feature makes it very convenient. The Bluetooth phone system is very clear to the person being called. A car to keep for a long time.
