With 15,000 annual mileage, I presume you spend some £100 pcm on petrol? Or perhaps small vehicles do not consume so much petrol nowadays? Providing you can install a wall charger, would you consider an EV? That will save you some £3,000 for the duration of the lease.
Id love an EV, we’ve got the perfect driveway for a wall box too.
The only EV for Under 25s that isn’t outrageously expensive (Micra EV and Renault 5) is the new Frontera, which I’m not keen on, there’s not even any other EVs other than the Puma Gen E and the Inster that are remotely close to being available for Under 25s but I’d have to ask with a pretty please for an exemption from the rules which I highly doubt they’d approve of.
