Is low mileage ever a bad thing when buying a car?

[matt-ITR]

So can low miles be a bad thing? I'm thinking cars that are rarely used and have very little mileage. Garage queens perhaps.

Cars are designed to be used and driven, so no doubt parts can wear/degrade out even when it is sitting there.
At what stage does really low mileage become and issue?

Extreme example would be the Porsche 959 found with delivery mileage and needed a fair bit doing.
Take less extreme examples, cars 5 years old perhaps. Any issues?

Pretty much as I thought, bit of a lottery at the end of the day but from the posts here seems to be an issue on cars 10 years and older, although not exclusively.
