I had one of that vintage. Transfer boxes area weak points and this one hasn't done enough miles to show the symptoms. Yours is also the vintage that suffers immobiliser grief. The theory was that mobile phone masts would interfere with it, but I don't knowing that was ever proven. All I (and a legion of owners) knew that the bloody thing would often inexplicably fail start until the RAC turns up and used their computer to resync the keys to the car.
If it's been stored in a dry and relatively warm garage it's a nice little buy. If its been stored any other way then the low mileage brings no advantage, and is liable to have more problems lurking than one that's been used regularly.
