Citigo Colour

Hi all, I'm in the process of buying a new Colour 5dr. It's already in the country so its being sourced. Which is good as I don't need to wait for several months. The dealer said it be a 66 plate, and was the new 17 model. From my limited knowledge how will I be able to tell. I seen some fairly new models for sale on the Internet, and from the internal pictures it looks like the new (17) models have the newer stereo display (colour display I think)
Is there anything obvious I'm missing.
Thanks
