That’s good as presumably you’ll be able to take advantage of the free charger from Mob being fitted. While there are some on here that run an EV without the ability I would say, on balance, it’s a clincher, especially if you’re mileage is AVG or above.
I’ve no experience of the Kona personally but they have always been considered a good EV, with both good range and economy. They are certainly well priced AP wise at the moment but don’t know if they’re entering into stock only territory? When are you due to change?
The Puma doesn’t have the battery size/ range of the Kona but depending on your driving habits that might not be an issue at all. If, like many, 90% of your driving is within like a 50 mile radius of your home and you only do a 200m journey two or three times a year then why cart a big battery around all the time?
Start with your needs (like the boot taking the chair) and your typical usage/mileage. This will give you an idea of what battery size/ range you need as a minimum and you can then start a list of cars from there.
