With the prices I've seen on the Mercedes connected one by importers here I have to think how long it would take me to make up that much money in petrol savings! They are neat cars though. Seem roomy inside.
one that has decent options goes for like 14k. like i said though, those cars are not about the mileage. its about parking them in the city. honda and toyota both have cars that are bigger,have more room in them and get as much or better mileage.
