In the recall thread NZPlusSix noted that his, and other Plus Sixes in New Zealand, have dropped a few cm on their springs since new. Sounds familiar.
My Plus Six used to crest the entrance of my garage with ease, but now scratches the muffler every time. TBH I thought it was my fault - having gained a few pounds in the last couple of years you see...

I'd be very interested to hear if the same issue is affecting other Plus Six owners as well. I've just checked my car - only 7cm under the silencer, which I suspect is an MOT failure.

Anybody else?
