Absolutely. Even if you clear customs through gray channels, local commercial insurance companies will refuse to cover third-party liability insurance due to the vehicle not complying with national traffic laws; additionally, the vehicle will definitely fail the annual safety inspection at the local DMV.

No, it is absolutely impossible to get a refund. Not only will there be no refund, but if the proceeds from the port auction of the abandoned cargo are insufficient to cover the exorbitant demurrage and disposal fees, the shipping company and customs will still pursue you (the bill of lading recipient) for the remaining debt through international legal proceedings.

Electrical faults are among the most annoying problems to discover after import, because they rarely stop the car from running. Ask the seller for a live video walkthrough testing each item: all four windows up and down, sunroof open/close, central locking (including with the key and remote), infotainment touchscreen, Bluetooth pairing, all cameras (reversing and 360-degree if fitted), parking sensors, interior and exterior lights, and the horn. Also watch the dashboard during startup: every warning light should illuminate briefly and then go out. A light that never appears, or stays on, tells you something needs attention. Pair this with an OBD scan to catch stored fault codes the seller might not mention. If a feature "only works sometimes," assume it is broken and price the repair into your offer.
