The Appeal

It takes a level of Mini-nerdery to know about Authi, the joint venture that British Leyland entered into in Spain in the seventies, and its locally produced version of the staple British classic. Their 1275GT didn’t adopt the Clubman front end that we got in the UK and it’s this version whose look this comprehensive restoration is modelled on. 

With a total spend of over £25,000, this car is the product of a labour of love. Starting life as a 998cc Spanish-registered car, it was completely rebuilt with an all new interior and £7,000-worth of fast road tuned engine.

The end product is a credit to its owner who, just 5,800km later, is reluctantly parting with it. This is a fantastic opportunity to acquire a one off Mini in fabulous condition and we’re confident that the winning bidder will have a whale of a time behind the wheel.

The Interior

  • Seventies-style bucket seats
  • Motolita suede steering wheel
  • Still in ‘just restored’ condition

While the louvred bonnet and the racy wheels hint at this Mini’s road race specification, when you open the door and see the seventies style buckets and clock the auxiliary rev counter, then you really get a sense of the intent of this build. 

Having seen relatively little usage since its completion, the interior remains in almost as new condition with no signs of usage anywhere. The seats and carpets are unmarked and the headlining is clean and taut. The three spoke suede steering wheel is still fresh and all of the dials, buttons and switches work.

Concealed under the dash is a Vintage radio which has a period look but packs modern internals and includes Bluetooth. In the boot it’s all clean and tidy too. In summary, there’s nothing to do inside before setting off to enjoy a drive.

The Exterior 

  • Bare metal respray in white under gloss black
  • Louvred bonnet
  • Two sets of pristine wheels

Although now five years since the completion of the restoration, the car has been stored in a garage under a custom cover for much of that time and so the paintwork remains in tip top condition. It’s managed to avoid any dents or scratches during its limited use and, although there may be one or two minor stone chips, you’d have to look very hard to spot them.

The car has been set up to run in two configurations: winter and summer, with a set of wheels and a bonnet (louvred and standard) for each. In practice, the winter bonnet has not been deployed however and remains wrapped in bubble wrap.

The seller reports that the underside is still very clean and free from corrosion and, with powder coated subframes, should be more resistant to the elements than most. Overall, this is one Mini that is bound to turn heads.

The Mechanics 

  • Road race spec engine build
  • Limited slip differential
  • Cooper S front disc brakes and vented rear drums

The spec sheet for the engine in this car is a dream for any fast Mini fan, as well it should be given the substantial bill for the work! Although cosmetically based on a 1275GT and badged as such, the owner chose to stick with the original engine block to maintain the matching numbers and so it has a capacity of 1078cc, though with an output that belies its size.

As it was designed to be used in the warmer climes of Spain, cooling was an important consideration which explains the bonnet louvres and white ceramic coated exhaust manifolds and also the inclusion of high flow water and oil pumps.

Starting is no problem due to a high torque starter motor and although the aggressive cams make it a bit lumpy in traffic, the owner reports that between 3 and 7,000 rpm it simply flies.

The straight through 3 inch exhaust makes all the right noises and the handling is very sweet, according to the owner, who thinks it would excel on a track, though he hasn’t tried it. This is clearly a Mini built to be driven and will surely deliver many smiles per gallon for the next owner.

A beautifully specced and well executed fast road Mini that is in prime condition and will be sorely missed.

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 Commission bids?

A commission 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.
