I have seen them as Red w/yellow stripes, Black w/siver stripes, White w/blue strips, and I think a green, and perhaps a silver.
If you have the kit I think that you have it is "just" an RT/10 is it not?
I think that the SRT-10 is a 2004/05.
Interior colour? Black w/grey perhaps.
You could do a search on it as well.
Hope that this helps.
