People have also told me that the aircon is the best way of reducing fogging, but mine doesn't seem to work very well, and perhaps needs some maintenance.
Perhaps I'd better see if I've got a heater too, though it sounds a pretty uncomfortable procedure.

Anti freeze slowly becomes acidic over time, and ends up attacking the metal and seals it is meant to protect. Anti freeze I typically recommend changing every two years, or 30,000km.
One thing to also check, which many service centres fail to recommend changing is the power steering fluid. This becomes very dirty over time, and can end up causing early pump and rack failure. Done every 30,000km, or two years max.
Another thing to have changed is the gearbox oil filter (I no longer recommend this on first and second gen Nissan March and Sentra, due to an assembly fault, which can cause more damage than good when changing the filter).
Many garages again fail to recommend this or carry out this task. As well as replacing the gearbox sump gasket, which helps reduce the chance of oil leaks and a wasted oil change, it helps to ensure that the gearbox is as free of particles as possible. It also ensures that all old gearbox oil is drained, as this cannot be completely done without removing the sump.
The gearbox oil filter is even more important to have changed earlier on many European boxes, i.e. VW, Benz, BMW etc. Many manufacturers claim that these filters need never be changed. This is NOT TRUE. These boxes fail at an alarming rate compared to those which have their filters and oil changed regularly.
We typically recommend most Japanese cars have their gearbox oil changed once a year, or 10,000km to 15,000km. For the fleets of Mercs we deal with, they almost always require their oil changing between services, at around 7,000km, at which point the oil can already become very dirty. Over 10,0000km and the oil can show signs of heavy particles.
