Hi @Marahute firstly I would say ignore @FartingInTheFence and his ill informed foul mouthed rants. EVs are rubbish, French cars are rubbish, VWs are rubbish... yeah really constructive input there mate.
Every discussion on EVs attracts a bunch of blokes (yes, always blokes) who think they know better than everyone else and go on about battery life, range and charging times, and how EVs are powered by coal and blah blah blah blah... yawn. Absolute rubbish all of it.
I bought a used Nissan Leaf last year (2017 model, 30kWh). We live in London so most journeys are easily within range (as are most journeys that most people do). We have an 8 month old DS. The boot is pretty big, easily fits our bugaboo cameleon. I wouldn't expect any issues with a family of 4.
It's a great car and there are many advantages of an EV as I'm sure you realize...
On a cold winter morning, no need to scrape ice off. Preheat the car from your phone, get into a toasty warm, ice-free car 15 minutes later. Or pre-cool in summer.
No need to detour to petrol stations, just charge up overnight (assuming you have off street parking).
Much more relaxing driving experience especially in heavy traffic.
No contribution to local air pollution. A great benefit if you do a school run. Cleaner air inside for your kids too, a lot of the exhaust in a normal car ends up inside.
Way lower running costs. Greater efficiency in traffic, unlike petrol cars.
If you like the Leaf, I would say go for it. You won't regret it :)
