Specifications and pricing correct at time of publishing. Prices are RRP before on-road costs unless stated otherwise. Always confirm with the manufacturer or dealer before purchasing.
Price Breakdown
The BMW X3 starts from $86,100 before on-road costs, while the Polestar 3 opens at $99,900. That makes the BMW X3 the more affordable entry point by $13,800.
Once you factor in stamp duty, registration, CTP insurance, and dealer delivery, expect to add roughly 8-12% on top of the RRP depending on your state. That puts estimated driveaway prices in the ballpark of $94,710 and $109,890 respectively.
