When sourcing used electric golf carts, the battery pack condition is the most critical factor; ask for the manufacture date and discharge test results, as replacing batteries can cost 30-50% of the cart's value. Inspect the motor and controller brand (e.g., Curtis or Moric) to ensure parts are easily replaceable. Additionally, verify the chassis material—aluminum frames are preferred in coastal areas to prevent rust and corrosion, while steel frames are acceptable for dry climates if they have been powder-coated.
