Strangely I was changing my car in September last year which is also around the car my policy is up.
I had to get renewal quotes for the car I had and the potential new car I was getting.
With my insurer at the time (Allianz) I was getting a similar renewal for staying with the car I had at the time, and I was getting about €150 increase to move to a newer car (moving from a 2008 1.9TDI to a 2016 1.6TDI so assumed it would go down)
But when I rang around I got onto Zurich and they were giving me a dearer quote if I was staying with the 2008 but about €100 cheaper to move to the 2016.
Someone on here presumably works in insurance and can confirm this, but all car types seem to be put into categories and quotes based on that, however there doesn’t seem to be uniformity across the different insurers on what cars are in those categories.
So definitely keep phoning around everywhere and you will find what’s best.
I found the likes of Glennon as a brokers got me a very good quote a few years ago, might be worth a try!
