If you don’t have any no claims bonus and are new to driving, I would think the insurance alone would be £1500 a year. In your situation I think Motability is the best route.
One top tip for new drivers if they insure their own car is to put an experienced driver (often a parent) as a named driver, even if that person never intends to drive the car. It massively lowers the risk profile. When both of my daughters were new drivers with zero no claims they had quotes for the first year of around £1,500 but with me added as a named driver that dropped by 50% to £750. After the first year that drops again due to the new driver having a years no claims discount and so on.
