Peter, I enjoyed reading your account of your factory visit and Plus 4 order.
Thankfully you don't have too long to wait to take delivery of your car.

With respect to the colour of hood and interior, that really is personal choice but I have a very interesting brown leather on my car and I wonder whether it would match the brown mohair hood better? I'll try to post a link to some photos; although if you like it, the best option is to order a colour swatch, to view it properly.
