V 50 for giants as commuters

Hello people, if I have driven a car in the last years, then my wife’s Golf V. I was lucky enough to work in my city and to be able to work with the bus or on foot. Now there is a change of employer and I will have to drive back from Nov 1. 75km to the workplace and 75km. The breakdown is about 5% city, 15% country and 80% highway, wobwi the speed is mostly limited to 120 km/h. Since we young people plan it should become a combo, then my attention fell to the V50. In question would be a one to three year old car. The price assumption is +-17,000 €. Since I have a few questions. Is the V50 suitable as a commuter car? Is it suitable for giants over 2 meters size? Which engine (diesel) would you recommend to me? Which equipment or equipment line is recommended? What does the retrofitting of a removable trailer coupling (for bicycle carriers) cost? Does anyone have a comparison to the current golf variant?
