The comments sections make interesting reading. There are some large bills related but also some interesting workrounds. I like the one about the £800 replacement rear lights when a 10p LED fails. A light cooking in a fan oven to melt the adhesive gives access, then out with the soldering iron- job done. (Cook the light unit, not the whole car).
Spares prices vary a lot depending on how/where you buy them- the threads are well worth reading if you're serious about one. Lots of VW parts, you just need to find out the equivalents.
No need to pay:
Discs for the front-2k each. (for the ceramic ones)
Pads ,front £1690 plus vat. ( -"-)
A quick search on eBay found a set of front discs and pads for £899
Rear lamp -£1400 plus
Still the air filters are only £100 each but there are four!
