Inspection Checklist for Genesis G80 Buyers

Test the "Ergo Motion" massaging seats (if fitted) to ensure all pneumatic bladders inflate and deflate correctly.
Check the operation of the rotary gear selector and the infotainment dial, ensuring they operate smoothly.
Inspect the vast array of interior electronics, including the rear-seat climate controls and sunblinds.
Verify the condition of the exterior chrome and the massive "crest" grille for any stone chips or damage.
On the Electrified G80 model, verify it accepts a rapid charge and the charging flap mechanism operates correctly.
Ensure the vehicle has a flawless service history to maintain the balance of the comprehensive 5-year warranty.
