I think the first one went back with about 9k on the clock, the second was 7k or 8k. Current one has done just over 6k and is due back at the start of April 2022 – though extension due to delays in building the replacement seems inevitable at the moment. Even so, it’ll be well under 8k.
On the other hand, even afterall the Covid restrictions my brother’s Golf will be going back (hopefully on Monday after an eight month extension) with about 62k miles on it.
