I run an 8 year old petrol-engined Mazda 2. I have full no-claims. My recent renewal was £351.58 with Roadside Recovery and a named driver, with LV. I will keep it going as long as I can, but it's entirely possible that my insurance will go up if I have to replace it. For many reasons, I will be getting another lean-burn petrol car. Modern cars are very expensive to repair, and EVs and hybrids are eye-watering to repair because even quite minor knocks can damage the integrity of the battery, and make them a fire risk. Lithium battery fires are horrific, so the garages have to store cars with possibly damaged batteries away from all their other cars in case the whole lot go up. Furthermore, independent garages are wary of them, and have limited access to parts, so the insurance companies normally specify dealerships. All of this is expensive. My neighbour sold her 17 year old Honda Jazz for a 2 year old hybrid Jazz. Her insurance leapt up from £300 - £1,300 after shopping around. It might be obvious to say so, but insurance companies are businesses, they have to predict risk, and you can see what the financial risk is by looking at comparative premiums. Some make policy decisions to get out of particular vehicles. They may refuse to insure, or else make the premium prohibitive. Caveat emptor!
