Most are little things that just annoy me. The stealer's customer service (or lack of) doesn't
help:
1. replaced all "R" badges as old ones had corroded (replacement badges have also now corroded)
2. new radiator fans, as slow speed fuse had blown
3. two new windscreens (on a two-year old car!), after they mysteriously cracked all by themselves - Seat accept no responsibility, Autoglass (who my insurer insists I use) says it is not covered by their lifetime warranty
4. silver bits flaking off the "Cupra R"
badge on the steering wheel
5. occasional misting inside the headlights
6. gear knob getting tatty
7. squeak/creak from the dashboard. Fixed once by replacing the dials, but it's back
8. (best one) when my first set of front tyres needed replacing, the stealer said they couldn't do it. They were worried about scrathing the alloys. Took it to a backstreet garage who whipped them off in no time (with no scratches).
9. mysterious creak from the offside rear.
There's probably other things that I've forgotten too........
