Hi there
It is a good source I am informed for £44,250 gets you a fully loaded car, so includes the BBS wheels etc.
As per last time UK will go for efficiency and as such the only options shall be transmission and colour.
So a grey manual car will come at £45,170 which is what I shall go for if get drawn from the ballot. As to what it will have exactly is a little unknown but it will have the BBS wheels, along with wireless Apple Car Play, but unsure if UK cars get JBL or not, I just see six speakers which I know the stock stereo has, 2 door speakers, 2 rear speakers and 2 tweeters, so guessing UK cars won't get JBL.
I guess it is down to the UK market been one of their best and as such they have to streamline the process a bit more by not allowing too many options, so in short we get to pick colour along with transmission.
