Looking for a winter hack as ive just sold my current motor ( i know its not winter yet but wont be long)

Theres a golf mk4 around the corner from me on a 51 reg. Its a 3 door and it has the PD 115bhp engine, its a GT TDi model.

Its done 155,000 miles, but has full service history and a load of paperwork and reicepts and hes asking £1500 which is a fair price as its clean and has nice wheels etc.

The question here is the mileage, are these good to go at that mileage or is it a mileage where things start to fall apart? It had the cambelt done not long ago. Just wondered what else to look out for?

Thanks
