Here is some info from one newbie to antoher.
I have decided to go with the Pilgrim Sumo (not yet started, just about to). And regarding the finish, as you can see on their website
www.pilgrimcars.com they have all the parts needed, plus there are different choices for some parts regarding of the style and quality that you want (standard or leather enterior etc). Of course, there are always parts that are standard and that can be bought everywhere like the tyres and wheels, so in those parts you have the full freedom of choice to get what you like best.
