Just a
guide for you
Early Leon mirror glass (Manual, same as MK4 Golf, Passat, Bora) is £18 ex vat
Late Leon mirror glass (Manual, oval type) is £29 ex vat
Bought a passenger side one today for my 2002 Leon (Early model) as soneone had knocked the mirror off
Had considered buying a set of late model mirrors but at a total cost of £268 for everything (and with my 20% discount) it was a bit expensive at the time.
Also thought about the MK4 Golf mirror glass with the blue tint. VW wouldn't supply me with any unless I gave them a chassis number. They told me that the glass would be about £25 a side for the manual ones.
