I translated the price sheets from the US Caterham site into a spreadsheet that covers the 280, 360, and 480 models. If you put a "1" in the quantity columns for each option, it will update the total price for you.
This is definitely not official. It was a manual translation and could easily contain errors. I just put it together so that I could play with options and see what the retail cost would look like. I thought I'd share it in case anyone else wanted to do the same.
