So ours has a manufacture date and I know people look at it and if it's older than 3-4 years they won't buy it off you, but as far as I can see that advice isn't anywhere in the manual of the seat. Maybe some seats "expire" in some way, but it sounds like an urban myth.

Don't think it's an urban myth, this article shows a car seat with an expiry date next to the manufacture date.
