Errrrm, do yo mean the 2022 Astra Hybrid plugin PHEV? With about 43 miles electric range....In your position, I would be buying a new Astra Hybrid, you'll be able to use it mostly on electric but it would not matter as much if you didn't get to charge as the petrol engine would see you through.
Price new circa £30k, and ok has a warranty. I'd cinsider one if I had occasional very long trups eg hols to do, but these days a pure EV should manage as more & more Rapids around.
A BEV should be a lot more reliable long-term, far fewer moving parts.
If you meant plain 'ole hybrid, the saving on these is really in around-town driving, where lots of stop/start means lots of regenning available. But the Li-ion batteryin these is usually tiny, say 1 kWh, good for 3-4 miles electric-only, and no ability to plugin to mains to recharge either.
