Mine did leak. DID. It took a while, but it is fixed.
And I wouldn't hesitate to recommend you buy one of these cars.
Like I've said before, I expect a little ingress myself in a convertible.
Mine is an '07 reg but the younger car you buy, the less likely you are to have issues I think.
Of course, there will be teething problems with any car you own, whether it be a convertible or not.
I say if you want a convertible, this is the best on in its class to go for. The Ford Focus CC3 leaks like a tap in 90% of the vehicles it sells, the Astra Twintop is ugly inside, the Renault Megane is two-a-penny, the Audi A4 is well out of the price range!
I really don't think you can go wrong in purchasing an Eos and you will be very happy with it like I am (now!)
