Hi
Have to say there is a lot of fun to have choosing the spec you want. I narrowed it down to 2 parts, a must have and a nice to have. You have to go and see and drive the different models.
Your questions
1 Search round the dealers they all book build slots if you want new find one with the time factor that suits you.
2 I like Mohair, yes it is silly expensive but I think it looks a lot better, others will disagree.
3 Colour the world is your oyster no two people will agree you have to keep looking at the mixes until one grabs you..
Above all enjoy the search and the owning of it.
