I agree about the wind noise - though I just ignored it, whilst it bothered my other half who then had a look and pointed out that the seals on the passenger and driver doors were different. Looking at it myself I can't believe I missed it - obviously a crap job has been done on the drivers door. Hope to get this sorted under warranty at the upcoming service.
One of the seatbelts in the back has locked - so that needs sorting out.
The interior controls are identical to my 147, which are fine, but I think look a bit dated now.
I had the META bluetooth option chucked in for free - don't bother it's useless, the quality is crap.
By far the best thing is the look of the car - I've never had so much attention to a car I'm driving as my Blackline. Whilst I used to think my 147 looked superb when I got it, I did think it was looking a bit dated towards the end, whereas the GT seems to defy the ageing process somewhat (at least until my head is turned by another affordable option!).
