My missus used her last two every day whatever the weather over a period of 5 years.

Mechanically it was never really a problem with either car, but bodily thats another story.

They are made out of papier mache and just rot.

So if you are planning on using it make sure you have waxoyled it to death, every orifice must be filled with waxoyle and do something to stop the battery tray rotting out and under the fuse box.

Then I'd go over the factory underseal with something to seal up any splits or cracks in it where water can get in and rot it out.
