Buy on condition and history how the car has covered those miles I would 100% buy a car with motorway miles than a garage queen had 2 GTi's a now mk6 dsg purchased on 14k miles sold on 90k it's now on 140k still all original parts never missed a beat.
Ran better and produced more power on dynos at 70k plus than when I had it!
My miles are mostly all motorway and b roads.
Current 7.5 GTi performance owned from new 2018 march done 61k runs better than when it was new.
At 70mph it is doing about 1600-1700rpm 7 speed dsg
These engines will run forever if well maintained then there is the ultra low mileage cars some have only been
Used and when taken out driven hard for short periods.
Each to there own but how the miles are covered and the car has been looked after would be my top priority when buying used.
Never let mileage put you off a well maintained GTI.
Also tyres brand on the car is a giveaway as to how it's been looked after cheap tyres uncaring owner imo.
