Rare K-Code Convertible: 1966 Ford Mustang GT

Even though it had been sitting for 15-years up until recently, this 1966 Mustang GT Convertible is a car that the owner says is ready to be driven home immediately. It appears to be a solid and rust-free classic with a very desirable engine hiding under the hood. The Mustang is located in Buford, Georgia, and has been listed for sale here on eBay. With bidding now sitting at $42,800, the reserve hasn’t been met.

The Mustang had been parked away in a garage until it was recently purchased from an estate sale by the current owner. The Mustang is nicely preserved, but it did receive a repaint in its original Candy Apple Red some 25-years-ago. I always find these older repaints to be interesting, because to my mind, if it can manage to remain looking good after a quarter of a century, then the work must have been completed to a high standard. One thing that will require attention is the rear bumper. If you compare the first two photos, you will find that the alignment of the ends is different from one side to the other. The paint on the hood has a defect or two, but otherwise, it all looks quite good. As far as rust issues are concerned, they don’t appear to be a problem with this car. The owner supplies a good array of photos of every aspect of the car, and it looks very clean. The top looks like it might be original, but it will require a replacement rear window. It also looks like it is quite dirty, so hopefully, this can be addressed without the need to replace the top.

The owner states that the K-Code 289ci V8 is very much the forgotten engine of the early Mustang range, and he is right to point out that the vast majority of people who equipped their Mustang with a 289 at this point in time chose either a C-Code or an A-Code. The K-Code is a bit of a beast, pumping out 271hp. This particular Mustang is a numbers-matching car, with a K-Code, 4-speed manual transmission, front disc brakes, and power steering. After years of inactivity, the resuscitation process on this car was performed properly, meaning that the car is ready to be driven and enjoyed immediately. All of the fluids were flushed and replaced, the Mustang was given a full service, and the master cylinder was replaced. The owner says that the car is ready to be driven anywhere, and enjoyed by its next owner.

The Pony Interior of the Mustang looks really tidy, with no real problems that would need addressing immediately. The carpet is showing hints of wear and discoloring, but the rest of the trim, including the console,  looks to be really good. There are no rips or tears, and the factory radio is still fitted to the dash. One nice touch is the fact that the interior features air conditioning.

This 1966 Mustang GT Convertible isn’t perfect, but it is in nice condition. From a features and accessories standpoint, it is also a vehicle that ticks a lot of boxes. The K-Code V8, Pony Interior, and air condition, all combine to make this a desirable car that should be enjoyable to own. With all of those features working in its favor, it’s little wonder that bidding has been so strong up until this point. I wouldn’t expect that trend to change any time soon.

    The bidding on this one makes the low mileage 5.0 foxbody mustang’s for 20k seem cheap.

    The “K” code Mustang is one sweet driving car. IMO one of the best engines Ford put in a Mustang. An easy 300 hp with headers and cam swap. I thought the world perfect in 66 and things couldn’t get any better, but then, 1967 came along and you get a Mustang with a 390.

    • 68custom

      Harry for my money the 271/289 is a far better package in a Mustang than the 390, now the 428 Cobra Jet that’s another story. A stang vert with A/C, four speed and the hipo small block and disc brakes is as close to perfect as a Mustang can get , to me!

      • RayT Member

        I’d stick with the HiPo 289. No matter how much more power the 428 CJ put out, it was also heavier and bulkier, neither of which did the “Stang any good.

        But for the money this seller wants, I’d want the hood straightened before I wrote a check….

    My dream car when I was 16, red convertible gt with hi po engine and 4 speed…or a 64 gto 3 deuces 4 speed convertible. Years later I got the goat, but it didn’t cost me 5 figures….these are too rich for me now.

  4. Gaspumpchas

    68custom is correct. This ones got it all. Good inspection needed anyway. Will be interesting to see what this beauty brings. Good luck to the new owner!

    What’s with the hood fit?

    • Rob

      looks like the hood hing was froze up and somebody tried to close it like that

    • steve

      Hood is bent, and driver fender is poorly fitted.

    Owning this car has got to be as close to great sex as you can get. Even in my seventh decade of life it still stirs desires in me just thinking about driving this car on a country road over hills around curves winding trough the gears top down on a worm spring day, I just can’t think of anything better, the pure exilleration, adrenaline pumping, clutch, engine and trans all in perfect harmony as I’m in full control reaching that point where physical body and mechanical engineering come face to face in full climax as a beautiful woman lying beneath me reaching full climatic satisfaction at the exact same time.
    God bless America

      wooo doggies Johnm…..Perfectly stated!!

  7. matthew B steele

    Beautiful car..id love to have this car..checks all the boxes..66 my favorite year

  8. Haig Haleblian

    Only Mustang I’d own 289/271 I can hear those solids tapping in my head.

  9. Barney

    Was factory AC available with the K motor? I can’t remember but I was thinking not.

  10. Scouting Ranch

    I can’t write how many people I’ve needed to correct concerning K code blocks. They were a basic 289 block, nothing special. I would take a k code over any big block, any…

    To go one step further. A ’64 K code Fairlane. Then, my life would be complete.

  11. Mark

    The Ebay ad shows the partial vin stamped in the block which is correct. K codes all had their blocks vin stamped. It is a 9 inch rear end in there too. Too bad we cant see the letters on the transmission tag to verify the correct Hi-Po trans.
    The issue is that no K code came with power steering or AC. Someone has added those to this car.

    • Kevin

      The seller is obviously very experienced with buying and selling cars like this one. If the car was not available with A/C or P/S from the factory, I think he should have disclosed that information.

  12. Del

    Yup. its rare.

    But before paying big bucks I would want Hood fixed and a new Vert top installed.

  13. Andrew Franks

    Well done, John. I’ll pass on the car. But not the girl.

  14. jerry z

    I’m surprised Gas Monkey Garage hasn’t purchased the car. Rich and Dennis should be all over this like white on rice!

  15. John Oliveri

    Nice enough car, till u hit a bump in the road and the old girl changes lanes , front suspension on these cars are terrible, brakes are even worse, 42 k I want something I can drive, and not turn into 62k, I just don’t see this kinda money for this car

  16. MrMustang

    Meh…give me a candy apple red 1967 GT fastback with the deluxe interior, deluxe exterior, 390 GT engine, PS, PDB, fold down seat, tach, turn signal hood, AC, Auto or manual no preference, and a 350:1 posi-traction. Never was a fan of the 65/66 because no big block in them. 271 hp pales in comparison to a 325 horsepower 390 GT. Like John said, this car is not worth what they are asking.

  17. TimM

    Nice ride but not for my pocket book!!!
