Hi mate
I did indeed use to own 147 - was a great car and enjoyed every minute of it. Went to the Prodrive meet last June and last years NBO and also took it to the Ring last October - although I guess you've already seen the photos!
It was super fast but I just didn't get the chance to use all the power that often - had wanted a WR1 for ages and now the itch has been scratched!
It was my daily driver as well but with a 50 mile commute was costing a fair fortune in fuel and also the 5000 mile services etc - if it was a weekend car would have kept it but saw a deal at Revitup (where I guess you got it from) did the deal and the One was gone.
Did you get the spare alloy? It has braided hoses and uprated barke fluid plus new front brakes but apart from that totally standard.
Enjoy it
Cheers
Si
