4 years and 30,000 miles on from New and still rated as best car I've ever owned. However on a recent trip, I had to drive on an unmade road in Portugal, during which a stone must have flown up from the wheel and cracked the sump pan. I cannot believe that Firstly, the sump pan cover is plastic, and Second, there is no guard. Result, a 434 Euro bill. Not a happy Bunny. Anyone else had this problem and is there an aftermarket guard supplied by any company?.
