This has probably been discussed here somewhere but has anyone taken their car through a car wash when a hardtop is on? Any thoughts?

 

It will leak. Not a big issue as you can dry it up with a small rag. I've done it before when I've been in a pinch. The leaks are mostly at the window seals, so take a couple rags with you and dry up whatever water comes in . Don't take your girlfriend or wife with you unless she doesn't mind getting wet

 

I'd assume an OEM or authentic Mugen should be fine. I have a Mugen and I get a very minor leak (drip) at the top corner near the windshield on the inside. I only do touchless car washes in the winter here so it's not something I'd probably do year round.
