Antara – Questions Long distance and family

Hello together, I’m just looking for a new business car, I’m a frequent driver and family father. After an E-Class, which I loved, I’ve looked around and find the Antara interesting (among many other things), just a little ‘small’.For that would be cheaper. Would be the Touareg, M-Class fan, but by a share of the rate and a CO2-bonnus/Malus regulation could be a proper payment due. Would it pack quite full (2.0Diesel, Auomatik, C osmo, etc), at the price. Unfortunately, I haven’t been able to test it yet, that’s still up to it. What am I asking myself: How wide is the rear seat, or the place ‘on elbow height’, or have 3 adults or 3 child seats or 2 child seats and 1 adult place? How loud is it? Can one still make reasonable phone calls at 160 on the highway? What about the long-distance suitability? Tired distances of about 400 or more km easy, or is it halfway through the seat position relaxing?
