nice to see another Touran owner. We have had ours since 2004, a 100/105 bhp 1.9tdi and are very pleased with it. With it being an early model we did have a few warranty jobs, but with 62,000 on the clock[I know it is not many], have had very few bills we needed to pay for. Namely a radiator fan, fan switch relay for in the car, and a couple of rear springs. The later are cheap and from what I gathered a fairly common failure. We must have been driving around for a year or so and had not noticed the failure.
We have towed a Triton, Troll, Camplet trailer-tent and our present Familia. All have given the best tow at about 50/55 kilos. At the 75kilos max I found the front end a bit light.
Fuel consumption is very good, but I am usually fairly light footed and found the published mpg figures achievable and have often bettered them. Your dashboard computer is a little generous in it mpg read but brimming the tank you will still be pleased. I have had 71 and 73 mpg solo at 50/55mph. Towing at 70 through France with a 1300 kilo Troll still saw me into the low 30s, whilst a true 70mph [read off satnav], 4 up and no van sees high 50's low 60's to the gallon.
