The Peugeot 206 in your post is in Group 7.
Remember that adding an older driver (with a good driving record) onto a young person's policy [as a 'named driver'] can cut the premium substantially (sometimes by as much as a third). It's irrelevant as to whether that named driver will ever actually drive the vehicle and, unlike 'fronting' (where a policy is taken out in the name of the older driver and the younger driver's name then added to the policy), it's completely legal.
Your pricing of the policy in Euros suggests that you're possibly in the Republic of Ireland, so some of this might not be relevant to you. However it's probably still worth reading:
