A few weeks ago when cleaning my car I noticed a perfect rectangle had been cut out of the cars insulation and carpet. To my suprise where this rectangle was cut, I noticed some very bad corrosion to the point, where it literally took no force to break off and now there sits a hole through the bottom of my car about the size of a 10 pence piece. This is right through the chassis. Ill attach a picture when I can. Whats weird is that the ar has only has door seals done since weve owned it, and we bought it when it was on 32,000 surely something a little dodgy here. I certainly didn't have anything done to do with it. The corrosion is right where the front jack up point is, but on the left hand side of the car, there is no corrosion at all at this point. More to the point, does anyone know what the cause could have been and what cost Im looking at to get it fixed. I can imagine its a straight MOT failure, but I can't anywhere on the net find anyone else with this problem?? It's a MK4 facelift fiesta Y reg, like I said ill post a picture when I can later on!
