Well the Spider was delivered back to us from HR Owen yesterday. Have to say I was impressed with the communication from HRO throughout. They've changed the hood motors (we must be on about our 4th or 5th set now) but seem confident that it won't fail again.
Finally brightened up this afternoon so we were able to get the hood down and take it for a drive. Happily, the hood worked OK (although it'll take a few more successful openings and closings before I'm convinced it's fixed) and was really good to enjoy the late sunshine with the roof down.
One problem though - when we stopped to put some stuff in the boot, the carpet in the boot and under the boot lid was damp, and there was water collected in the seals. Then, when we put the roof back up, it dripped water on us - turns out the *inside* of the roof was wet, mostly close to the rigid plastic bit that mates to the header rail. The outside of the roof is bone dry, as is the spare wheel well under the boot floor. I put the roof halfway so I could check inside where the roof lives, and it was all dry in there too, so I'm not sure what's going on.
I might stick this in another thread in case anyone else has experienced it and knows what's going on. In the meantime, I've dried it off best I can and will keep an eye on it!
