do the dash surround in a nice glossy piano black finish. It's a great colour and not over the top.
And with the boots, it really depends. If you are going to get you seats retrimmed aswell, go for whatever colour you want to do the seats in, and if you're not going to get them retrimmed then go for black.
And also with the door trims don't do them white. Once again do them black unless you're going to get the seats retrimmed aswell.
I think that you should do the dash surround in a nice glossy piano black finish, and them do the seats/door trims/boots in something like red leather.
Post up pics when you've made your choices and got it all done.
