More questions from little old me!

If I were to entertain the Escos Rep idea, as I obviously can't afford a real one and don't like S2's, and wouldn't really go for an S1 for a couple of reasons, which would be best to start with: mk5 RS2K or mk5 XR3i?

If people could elaborate on why either is better, etc

If I went for it, I'd like to put an RST lump into it. What would be involved? Seems I could get a fairly cheap base car and I'd go for sorting the mechanics before the styling, be that regular escos or wrc style.

Cheers folks, I appreciate it.
