I took part in a Product Training for X5 F15 and 4 Series Coupe and in the evening event, we could admire the i8 - phones or cameras weren't allowed so no pics!
We were also shown the 2 Series Coupe and 4 Series Cabrio.
2 Series was sapphire black with coral red interior - it was a 220d
4 Series Cabrio was Melbourne Red with Sport Line - Black leather and red accents/stitching
i8 was Ionic Silver - but we couldn't see the interior - and it was a production car for USA.
The event took place in Vienna, Austria.
