Information about the model

Mercedes-Benz Vito is the newcomer in the commercial vehicle range category where models like Transit are already ruling the market. But, it is not a surprise to see the forerunner in the motor car maker be interested in releasing the Mercedes-Benz Vito model of the car. A lot of them tend to confuse themselves between the Vito model of Mercedez Benz and BMW.

Mercedes-Benz Vito W638: First Generation

Mercedes-Benz Vito W638 is the range of car which combines both the features of a minivan and a car. The dashboard and the control features of the vehicle look like that of a car to give the luxury feel but the capacity of the vehicle resembles that of mini vans.

Three lengths are provided to the car. Based on your requirements, the size of the car can be decided. The high roof model is not incorporated into the design of this vehicle, that the design would get completely modified like that of a mini van. The hill start assist feature included in the vehicle makes the travel uphill a very easy and smooth ride.

Apart from the exceptionally good cargo space, the load capacity of the roof of the car is also top-notch. The airbags, interiors of the car, the strip of LED in the cargo area makes it one of the best to suit all your business needs. The first generation of Vito has very good engine capacity and also the wheel design makes it one of the top choices for sharp turns.

One could clearly say that Mercedes-Benz’s venture into the commercial vehicle category has certainly captured the attention of all the buyers. With its exceptionally good features, it has gained a very good market all over the world. Vito is a bit on the pricier side, but one could get what they had paid for.
