It's reasonably cheap and very easy to mount. I simply walked into the spare parts warehouse at a big SKODA dealer (AB MONS in MONS, Belgium) and asked the clerck to look in his computer if they were in stock. Yes, they did. 5 minutes later, it was in place, the man did it himself with the aid of2 screwdrivers. Always nice to have a pair of reserve glasses with you; coming home from the trip to MONS, I fell on my face in a gas station
and broke my usual pair; nice to have a spare pair under your hands then, without having to search half your car. Beware: they come in different colours!!! Choose the one matching your roof covering.
