Our team's primary aims are to source the most unique items for our auctions and to make participating in our online events enjoyable and easy for our buyers. We endeavour to do this whilst offering a personalised service to all.


Step 1: Register to Bid

To register as a bidder, create an account on our account. You'll be asked to provide your credit card details, and a temporary charge will be placed on the account for the duration of the auction to minimise fraudulent accounts from interfering with the bidding process.


Step 2: Place Your Bid

Items at auction may be sold with or without a reserve price, and will be clearly identified as such during the auction.

For a sale to be successful a bid must equal or exceed the reserve. In the event that you are the highest final bidder, but the total bid remains under the reserve price the item will not sell.

Popcorn Bidding: All lots use a 5-minute time extension system. If a bid is placed within the final 5 minutes, the lot’s end time will extend by another 5 minutes. This can continue for up to 24 hours after the original closing time.

Items that are sold without a reserve will be clearly identified as such during the auctions. In their case the highest final bid will always win the item.

Items that do not meet reserve or do not receive any bids will not sell. Upon the closure of the auction these will be removed and managed independently by our specialists. Interested parties are invited to engage with our private sales team to make an offer.


Step 3: Make Payment

We pride ourselves in offering our customers a variety of payment options to satisfy their preferences. Upon conclusion of the auction the F1® Authentics sales platform will automatically issue a payment link to the winning bidder.

Payment is due in full by the end of the first business day following a sale. Proof of payment will be required and requested by our specialists.

Auction hammer price is exclusive of buyer's premium and sales tax, and exclusive of import duties and VAT.

All invoices and payments will be in Great British Pounds (GBP).


Step 4: Lot Shipment

Memento Exclusives operates with several reputable logistics experts. Our partners have experience coordinating the worldwide shipment of valuable and delicate vehicles and collectibles and will ensure products are treated with the utmost care.

Upon conclusion of a sale our specialist will contact the winning bidder to discuss delivery options. Air and sea freight quotes can be produced for items.
