I understand this decision, especially if the MG ZS EV is your only car. I purchased our MG as a second car, replacing my old ICE vehicle. My wife has a Mazda CX-5. However, it took a lot of thought and an honest analysis of my real-world driving before I committed. I only drive locally, so the 250-270 km range I get out of the MG is perfect for my needs. I only charge once a week. Our weather is never very cold. In fact, for me, the battery cooling system was a selling point, because it gets really hot here.
My wife has started using the EV for local driving instead of her ICE, which only really gets used now when we are out separately at the same time, such as going to work.
But - and this is a big one - our ICE vehicle is available for our rare long trips away. The charging network in Australia isn't good enough to support certain long journeys. Up and down the coast isn't too bad, but inland is abysmal. For example, our annual trip from Newcastle to Cowra, which is about 475kms each way, would be possible with an EV but terrifying. Nowhere near enough charging stations for my liking. But a trip to Sydney and back is fine with a single charge in the city.
But, as I said, 99% of our driving is within 30 km of our home, so the MG EV is great for us. I regularly drive from the Hunter to the Central Coast regions in NSW (about 105 km round trip), which the MG handles without issue on a single charge and without range anxiety.
Many of our acquaintances, and even a few friends, are skeptical of (and occasionally hostile to) our EV ownership. The skeptical ones ask whether I'd recommend an EV, and my answer is "No". Because I don't know their specific circumstances, any more than I know whether a specific ICE vehicle suits them. The Suzuki Swift is a great little car, for example, but wouldn't suit a family of five. The MG ZS EV fits our situation perfectly because I know our situation perfectly.
If we had one car, we would have needed an EV with 100km more range, a cost that I couldn't justify. If the ZS EV hadn't been released in Australia, we would have bought another ICE vehicle.
However, with ranges increasing and EVs getting cheaper, I imagine in the next 5 years we'll replace my wife's Mazda with a higher range EV. It's inevitable. I've been keeping an eye on future planned releases of BYD EVs in Australia, for example. Or maybe the MG Marvel R, if it comes here.
EVs will catch up with your needs at some point, Peter, and you'll get back in.
