Which VW is best suited to the long distance?

Which clean VW diesel is best suited to the long-distance route? A little over 30,000 are planned for the year. Treasures are so generously rather 33,000 Maybe even less. Price age and budget are first of all minor. I would only like to know which model would be the best to arrange. I like the Passat and Golf Kombi as GTD, the new Tiguan of pictures, the Golf Sportsvan, the Touran also the new one. What do you think?
