Things are looking up a bit. Although the parts are not due for another month, after a letter to Slough, communications have improved and they are getting a Brera to the dealer for Friday for us to use while ours is fixed. Have offer of a free first service and a few more sweetners. They are also replacing our alarm sensor as per another thread on this forum.
After the response today I feel a bit more loved.

Sooooooooo we'll have a Brera back , if not our own and at least someone has listened!
The wiring loom is still a far off hope for delivery though.
