Rear Wiper - yeah, sort of noticed that was missing, thought it was a little odd
That strip of curved perspex your talking about under the rear rear window/boot lip spoiler is a bit odd, i can see what they were trying to do, but it failed, and on the newer CLC that replaced this, they removed it completely and left it solid, which i'm not sure if that was a good move or not, given the choice of having it or it being solid i'd have that perspex strip !
Not noticed the boot thing dripping on my head yet, although i was sort of used to that with my old car, so maybe just not noticing it, i have noticed it can like to drip inside at times when open, again another thing my old car did
The facelift interior is a huge improvement your right.
