Id give Dixon a call... but I am absolutely certain they only offer it on the 1.2 Dynamique.
When I bought my Dynamique in 2001, they told me it was the only car you could get it on, and then a month later, a friend got free insurance on the 1.4 Dynamique in Newcastle. I questioned this at Dixon and they told me it varied dealer to dealer.
Then recently (in last two or three months) a friend of mine bought a 1.2 Dynamique new, and they were told the same thing.
