This neat device attaches to the headrest stalk and keeps your seatbelt where you can get to it instead of having to scrabble around behind the seat for it. Suitable for both the GT and roadster with the single post headrests, this really does work and has my wife's seal of approval and that isn't easy to get. It's made from moulded plastic and has the MG crest on the front and rear.
As all it does is guide the belt, it doesn't affect the safety or operation of the belt in any way. We gave it a good test today with a run from Stokesley to Helmesley, which anybody aware of the road will know is a twisty road with some steep climbs and descents. Even with some spirited driving the belt stayed in place over our shoulders and we both felt comfortable with it.
We met some friends in Helmesley and showed them the holders. They were impressed too and wanted to know where we got them.
They came from a US enthusiast who makes some neat accessories for MGs and some other cars. Website is www.clarkandclarkinc.com

I have no affilliation to this company. I'm just a very satisfied customer.
