I have to park under a tree every day, and I get a lot of leave down into the softtop. After a year of this I'm sure there's plenty of old leaves stuck in the drains. So how do I get them out?

 

I have no idea, having been a S2000 owner for about 45 HOURS myself, but this sounds important. For my Miata, I made up a tool of a small brush, about 3/4" diameter by 4" long with bristles all the way around, and wired the handle to a straightened coat-hanger, so I could shove it all the way through the drain until it hit the pavement. Works great.

However, it hadn't occurred to me yet (give me a break, I'm new) that the S2000 has drains too, now I have to find them.

 

This has been discussed on Wash and Wax. Great advice can be found here

with top part way down, you can see pretty much all of that area...
vacuums can be the solution (first vacuum the area out then, use the blower side to blow out what you cant get out with normal vacuuming)
that should get it...
post back and let us know how it goes-
but the secret is to let the top down part way...
