I’ve had a mark 2 since 2014 and some time ago came up with a little mod to attach a strap to the soft top hand hold which allows the driver to raise and lower the top without leaving the car. I wrote it up in the form of an ‘Instructable’ - hopefully it might be of interest
The NA has basically the same roof as the NB. Being one of the 1 in 10 means the lowering handle falls easily to hand in the RHD market. For LHD markets, the opposite applies.
Purist NAs will also have to deal with unzipping a plastic window.
Did similar thing to my nb when I had it as I could not turn around easily. I did not go to the exotic way you didI simply rmoved the cover an fitted a piece of belt to it and screwed the cover back into place.Also put piece of adhesive velcro on belt and top of winscreen surround to keep strap out of field of view when not in use
I raise and lower the roof in my mk2s from the drivers seat with my left arm but its a bit more awkard with the bucket seat now so may consider something like this in future!
Found a couple of hex head bolts of the same thread pitch and appropriate size. Left both parts of the strap on initially to see which was most ergonomic.
