Currently, there are not many specific aftermarket parts available for the Polestar 3, but some companies are starting to offer accessories and upgrades. For instance, ECOEVS provides a range of interior and exterior accessories like all-weather floor mats, seat protectors, and exterior car covers, which can enhance both the functionality and appearance of the vehicle. Additionally, EveryAmp offers 3D-printed aftermarket accessories, although their selection is more focused on the Polestar 2, they might expand to the Polestar 3 in the future.
Genuine parts and accessories from Volvo are also available, which can be a good option for those looking for official upgrades. However, the market for aftermarket parts specifically designed for the Polestar 3 is still developing, so it might take some time before a wider variety of options becomes available.
