I agree that the condensation is probably worse than other cars I have owned. I have a feeling that it's to do with how the water drains into the area below the plastic shield under the windscreen. This is also where the air intake for the heating is so that moist air is being drawn into the car. I have checked for door seals and they look water tight.
It could also be due to the fact that it has been a VERY wet winter with relatively high temperature so that air humidity is high. (See also other thread about condensation in headlights)
The solution I posted about when this was discussed before is too run the air con all the time to dry out the inside of the car ie fabric, carpets, insulation etc. The cost is pence and compared top letting the car idle on the drive and drive off with a letterbox view of the road is easily the best solution. One small scrape will cost 1000s more than running the air con. Plus you preserve the air con seals by lubricating with the air con gas. It's generally reckoned that air con should be run for 20 mins per week to prolong it's life and avoid regassing and other
repairs if you only use it when outside temperature is hot. My ultimate driving machine says run at all times above 5 degrees C which I don't do but I do run regularly once the car is up to temp and on dual carriageway or motorways when the extra load is tiny in comparison.)
