It's on a 20 reg 1.5TSI 150PS estate (Manual). I've enquired about service history and I'll ask for confirmation of mileage history, but 25k in 3 years wouldn't be a surprise.
It would be good to know about the previous owner but I'd be surprised if the dealership give me much on that.
Hmm, that maybe suggests that if its a one owner car, it has done basically 60k in 4 years, which would average out at 15k per year each year. Hence my suggestion that the mileage was incorrectly recorded as 25k on the first MOT when it could have been 45k, then another 15k-ish 12 months later on the next MOT.
As far as previous owner details, you have no chance due to today's GDPR rules - even if the previous owner leaves receipts etc with the car when sold, the dealer is duty bound to remove them to prevent disclosure of the previous owner to whoever buys it later
