Fair point. I guess it just depends on your personality. You're much more laid back than I am. I expect that if I'm paying £30,000 for a car, then it shouldn't leak. I am also a bit obsessive and so really want to know why it's leaking, if it's a design flaw etc. I guess some people won't be bothered by this, and some people will. Hey ho.A slight amount of water ingress is not a deal breaker in my opinion. Plus why would you waste time taking you car to the dealers 4 times instead of taking advice from other owners that have easily solved the problem? I don’t understand.
