1983 BMW 635CSi Manual


  • Rare 5-speed manual gearbox
  • Limited-slip differential 
  • Great potential


While BMW has become one of the most popular cars on the road these days, it wasn’t always the case. Go back a few years and you can see how they started to make their mark, with beautiful aesthetics combined with that exceptional German engineering. One such example is the stunning 635 CSI which have become very collectible in recent years, for the afore mentioned reasons but mainly because they are now such a rare beast. 
Among those rare, are rarer still. There were not many that came with manual transmission like this one, but this one also came with a limited-slip differential from the factory. 
The current owner has given this one a thorough service and new radiator with the intention of restoring it completely. Unfortunately, the loss of storage space means someone else will need to finish the project. Previously stood for some 20 years by the previous owner, it will require a thorough restoration to bring it back to its former glory.

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.


C&C 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 £10,000 £100.00
£10,000 to £50,000 £250.00
£50,000 to £100,000 £500.00
£100,000+ £1000.00

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.

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.
