How should I handle “how to compare stores for gmパーツストア近く” when shopping for “gmパーツストア近く”?

For “gmパーツストア近く”, call before traveling. Give the VIN, exact part description, and old part number; ask the store to confirm physical stock, hold time, condition, price, core charge, and return rule in writing. Compare the complete pickup-and-install outcome, not distance alone. End with a go / no-go rule the reader can apply without jargon.
