Update:
Honda at Grantham had a look, as professional and courteous as ever. Then called for their approved repairer, seemed like a knowledgeable chap, both agree that this is warranty work. Just Mr Honda to convince now, with the wonder of a digital picture or two. Anyway, if this is approved (and it f***ing well better be) the repairer said that this will be in excess of £1500 because of the complexity of the work. Basically, it's all the rubber and plastic seals off the roof and a pillar, then inside trim out to try and find the cause, if it's well gone it's a new roof :shock: and then all to be sprayed up to match the rest. Oh yeh and the screen comes out too for this.
All in all, I am well hacked off about this, this should not be happening on a newish car :cry: The worse thing about all of this is that I am gonna get a bastid Jazz again for a bloody week or so. :x
