The Appeal

 It's often said that the Sunbeam S7s were just about the world's most over-engineered motorcycle. Rock solid, loaded with innovation and carrying an engine assembly that was close to those fitted to a motor car than a bike, these remarkable pieces of kit have become highly prized - but did have trouble on the market. Innovation wasn't cheap. 
That means that the S7 is immensely prized by the modern market. They were, after all, like no other mount from the era, and continue to act as a gold standard for mid-century biking. 

What makes this motorcycle truly special is its comprehensive nut and bolt restoration, with many new parts sourced from Stewart Engineering and an impressive history file accompanying it. The results speak for themselves - this remarkable bike won First in Class at the 2024 Fraserburgh Vintage Car Rally, and is now ready and waiting for its new owner.

About Max Bids

The max bid process allows you to bid without any hassle.

Enter your maximum bid and we will then bid on your behalf to ensure you're the highest bidder - just enough to keep you in the lead and only up until your maximum.


Car & Classic prevent auction snipers from bidding in the last seconds to win an auction.

Auctions are extended by 3 minutes if anyone bids within the last 2 minutes to allow other bidders to react and counter-bid.

Auto-bidding increments

  • If your maximum bid is equal to or below the reserve price, your maximum bid will be applied in full if you are the highest bidder.
  • If you are the highest bidder and place a maximum bid above the reserve, we will automatically put in the reserve as your first bid.
    • Once the reserve has been met, Car & Classic will make sure you are the highest bidder using only the bidding increments stated below.
    • We will keep you in the lead up until your maximum bid OR the increment closest to your maximum bid, providing your maximum bid is enough to cover the increment value.

Bid Amount Increment
£0 to £9,999 £100.00
£10,000 to £49,999 £250.00
£50,000 to £99,999 £500.00
£100,000 + £1,000.00

Automatically outbid immediately

When you place a max bid and are outbid immediately that means that another bidder has placed a max bid limit which is higher than yours.

You can bid again and we will use our automatic bid system to try and get you as the highest bidder.

Matching max bids

When there are two max bids of the same value, the one placed first remains the lead bidder.


We may hold a pre-authorisation charge on your card until the end of the auction when the hold will be cancelled. If you win, we'll take a security deposit which counts towards the payment for the vehicle and isn't any extra cost to you.

What are pre-bids?

A pre-bid means you're able to place a bid before the official start of the auction.
You will be notified whether or not you are the highest bidder when the auction starts.

Problem with your bid

Bids are contractually binding. To help protect you, we have some rules in place if we think it's been mistyped. Please check and amend what you have entered.
