Yeah that magical 100K mark is so weird. I don't get the stigma. My S8 is on 113K which for me is low mileage - my A6 made it to 360K and my current A4 is on 280K!
When my housemate bought her TT with 140K several people commented on the 'high' mileage. What do they expect for a 14 year old car?
It will be nicer and faster and better in every way than their brand new soulless ****boxes until the day it dies.
