Mine had only done 5000 miles in its first 10 years, I knew the likelihood of several issues arising so I insisted on a thorough check and derive before delivery. Needed new catalytic converter, new egr, new water pump, several new hoses, brake and calliper seals and a few other bits and bobs too. Would have come to around £3k including labour. Done 1800 faultless miles since purchase and hope for a couple of thousand more this year.
In my opinion a low miles car can be fine but buy from a dealer with a decent warranty or a decent service history and at least proof or regular use.
