What year did the catalyser and closed loop injection start?

Hi! I picked up this lovely 2006 model in the UK.

I'm curious- how do I find out if it has a cat and/or the closed loop injection system? Is it possible to decode the VIN?

I've read that the later versions are a bit more frugal, but I'm sure of the changeover year

2008

This is a 2008 model listed on ebay that I'm interested in- can anyone tell if it's a closed loop model? Can you spy the O2 sensor?

This black wire coming down from the body panel leads to the O2 sensor.
