I went from £400 a month fuel spend to just over £100 going to hybrid. My insurance came down from £700ish to £450 p/y (all the anti collision toys etc). The services were 4-600 a year now 250-300. It’s been 4 1/2 years and I’m keeping it. It cost me about 10k more than I’d normally pay for a car and I reckon I’ve made my money back and then some. That anti collision stuff has also saved my arse a couple of times.
