My Drive: Seat Ibiza 1.5 evo Just wondering with limited time to carry out lets face it. An ever expanding and complicated MOT test. How is the underside accessible? As It is coved completely in flat black plastic covers. OI understand there are many reasons for this. Such as underside corrosion protection from stones and salt water spray, fuel saving, Maybe some sound deadening. Seems a better idea than underseal. Which has many drawbacks and problems I have not looked how these panels are fixed on? I take it is with many toque screws? So how will the MOT tester be able to do their customary poking around for rust and hammering with their rubber hammer. Which seems to do more damage than what they are actually trying to find? I am sure that they will not refit this back properly. Also what happens if the screw heads get full of mud and crud. Also corrode into place as the years progress. It will be interesting to see how the Ibiza stands up to corrosion? As VW products seem to be pretty good on the whole. I have had experience with a few rust bucket Fords. Maybe these covers will help. Or maybe they will make situation worse with water, salt and road dirt traps. Not letting the air dry the underside out quickly.
