Now here's a one-of-a-kind garage sale: Bentley Motors is looking to unload some original and unused parts and accessories.

The automaker is opening up its headquarters in Cheshire, England, on Sept. 26-27 to pro buyers, owners and enthusiasts. The sale will feature about 7 million items. The list ranges from a V8 engine block to a replacement gearbox to an indicator bulb and an illustrated 1950s handbook. Rolls-Royce parts will also be available.

Bentley is hosting the sale to clear out space for the upcoming Continental Supersports and the new Bentley that debuts in August.

Factory-trained experts at the sale will help identify and find the correct parts. Also, the parts will be sold with a manufacturer warranty and branded packaging.
