My daughter in law took her Mazda MX-5 for a service this week. It's about eighteen months old and she has had it since June 2020. Due to lockdown, though, she's not driven too much.
The dealer rang her to say that there is a build-up of rust on the brake discs and, whilst not dangerous, they could do with skimming/cleaning to remove the build-up at a cost of £260. Should anything like this have been picked up before she bought it? Is this also likely to be true of most cars which are not driving as much as normal? Thank you.
