I've had some experience with the Polaris GEM, and they're quite popular for short-distance commutes and errands. In terms of performance, these vehicles are pretty capable for city driving, with top speeds typically around 25 to 35 mph depending on the model. They excel in environments where you don't need highway speeds, such as college campuses, resorts, or small towns.
The range usually sits between 30 to 100 miles on a full charge, which should be adequate for short trips and errands. However, keep an eye on the battery health, as range can decrease over time. They handle quite well on smooth roads, but they can feel a bit rough on uneven or gravel surfaces given their suspension setup.
Regarding maintenance, GEMs are generally low-maintenance compared to gas vehicles, thanks to the simplicity of electric drivetrains. Still, you'll need to keep up with regular checks on the batteries and brakes. In terms of reliability, as long as they're well-maintained, they tend to be quite dependable.
When compared to other small electric vehicles like the Renault Twizy or even golf cart-type EVs, the GEM offers a bit more in comfort and features with enclosed cabins and optional creature comforts like air conditioning.
One thing to consider is your specific use case and local regulations, as these can affect where you're legally allowed to drive a GEM. I hope this helps! Have you checked if there are service centers nearby in case you need future support?
