Engine freeze plugs, and nothing else.
Possibly the most reliable used car I have ever bought - virtually no repairs in 40K miles of driving.
Just a quick "must look at" for all wagons fitted with factory roof racks. If the roof is showing rust color from under the mounts of the roof rack, remove it ASAP as the holes put in the turret to mount the rack aren't painted prior to fitting the rack. In Australia we call the mounting bolts used "rawlnuts", and they are a rubber encased brass thread. Don't push them in, pull them out, paint and replace the rawlnuts for another 20 years of happy motoring. If you don't these holes will open right up as they are already nearly half an inch in diameter.
