Used the car yesterday for the first time in a week. Boot was covered in 2 inches of solid ice and would not open.
Wasn't too bothered about that, just put two massive bags in the passenger bit.
Later, doing 70mph on the dual carriageway, I suddenly thought, mmm, that spoiler isn't going to come up.
Nothing happened, but it did get me thinking.

Anyone else looked into this and possible results?

I have had a look on the RCZ forum, but not really any advice. Although they did mention the complexity of having frameless windows when it is frozen.
Which is another problem I did not know about.
