Hi, I had Touran family se auto for four years, travelled around 40000+miles.
Would not bother with sun roof not used that much.
Me personally would if you can afford the AP go for R line dsg the climate control is better than air conditioning.
I have had three Tourans always dsg, brilliant and relaxing to drive long distant like 2/300 miles no problem. If you need any further info you can contact me om michaelsportraits1@gmail.com
I have gone this year for a smaller car vw t roc r line as my needs are less otherwise I would have stayed with Touran, cheers Michael
