Very much doubt Seat could claim fair wear-and-tear. An issue re leaking door seals was highlighted on this forum as far back as October 2001, which was a mere two years after the Leon's launch.
And as mentioned previously in this thread, there are plenty of examples of VW Group cars that are over 20 years old - eg Mk2 Golf - which to this day have never leaked.
Mate I'm completely on your side as I say I've just been through the pain of having the fixed elsewhere as I'm not mechanically minded either! I'm just saying it wouldn't surpise me if they did. When has there ever been a recall on cars so old?
