That's what I thought when I looked at it and he pointed out the screws he'd removed.

The handle is combined with the 4 leccy window switches. All seems tight and couldn't see a way to pry apart without buggering his tidy car so didn't try it. It does look to be 2 pieces though, and like you I wonder if part of it unclips, revealing something like 2 large screws or bolts holding the card on.

Maybe I should attack with a screwdriver and see?

Thanks Ollie - anyone else confirm his suspicions before I do bugger the handle with a sodding great screwdriver?
