evaluating rules, resolving conflicts.

Imagine a system where you could say:
"blue cars have white seats"
"Cars with white seats have black stitching"
"Red cars have white seats"
"Red cars cannot have black stitching"
"Red cars with four seats can have black stitching"

I've a solution which will cope with the above, but I can't help feeling
it's a bit lumpy.
The reason I'm posting here is that I'm looking for an OO solution using
..net2 which can cope with me dropping the odd van in there that has
black stitching. I think I've mapped out the majority in my head, but
I'm sure this is one of those problems that comes up daily that someone
smarter than me has solved with an elegant pattern.

As much as I like .NET, the right tool for this job is Prolog. (I don't
think that there is a .NET implementation for Prolog).

This sort of problem is exactly what Prolog was invented for.

Always use the right tool for the job

Sounds like Prolog.
