I own a 2012 golf tdi highline wagon. As mentioned in a previous reply, the back seats do fold flat if you take off the rear head seats (which I have done to accomodate my lab). Appearance is personal and I really don't mind the look of the wagon (and the new 2014 version coming or 2015 depending on when it lands here is even nicer). The mileage is great with the diesel and the cargo room is sufficient and better than some competitors SUVs...
I too, had a flat tire and had to call roadside assistance on a Saturday, who told me not to drive on the highway with the spare so I had it towed in to the local dealer and left it there for the weekend....the service guy was upset that I did not put the spare on it as he did not wish to come and get me at home (about 15 miles) and pick me up to retrieve my car as there was no such service....the new tire cost me a total of $350. ouch....
My main issue with this vehicle has been poor winter performance. My car does not like winter at all. With no AWD and little ground clearance, (and I did not purchase snow tires), the car was scary during snow or ice storms....I did not feel safe....having come from a 4WD SUV jeep, I would have purchased an AWD version of this diesel wagon had one been offered (I see that one will be offered in Europe in the next version of this car but not in Canada which makes no sense to me but is apparently due to the fact that the mexico plant can't build an AWD vehicle since it is not set up for that...well, how about setting it up....this is Canada and I live in Northern Ontario where the roads are snowy and icy from at least December to March)
Also, during this cold winter, the battery went dead on me on several occasions, even when plugged in some times....so again roadside assistance was called...they checked the battery at the dealer but it did not show any signs of trouble....another cold night, found the defroster ceased up until it was warmer outside in a few hours.......a heated steering wheel is not available but would also be a great feature....I am considering trading this vehicle in because of the poor winter performance (even with snow tires, I still won't have much ground clearance and the battery and defroster don't seem able to cope with the cold winters....(I have no garage)....good 3 season car or 4 season if you live somewhere where snow and ice on the highways are not an issue....at least, this has been my experience...
