I got a used, early 2019 HSE First Edition. The FE is really just a fully loaded HSE with some lettering on the dash and sill plates.
These vehicles are actually far more different than similar. The handling, steering, suspension, and overall driving dynamics of the I-Pace far, far exceed the appliance-like ID.4. Don't get me wrong though, some times and some people might actually prefer the don't-think-about-it aspect to the ID.4. The ID.4's turning circle is so good that the I-Pace feels like a boat in tight quarter turning.
The I-Pace hasn't aged a day. The build quality, materials, and workmanship are truly top-notch. Thanks Magna. I had a modern loaner ICE Range Rover Velar recently, and that vehicle felt like pure trash compared to the solidness of the I-Pace.
As for efficiency and range, the battery shows very little degradation (about 82kWh down from 84kWh new) at 40K miles. The winter efficiency is better, actually a lot better than the ID.4 in all cold conditions, especially when you can leverage heat pump with preconditioning.
