The Humbler: 1970 Pontiac GTO Convertible


It’s pretty obvious that this one has been put away for a while–since 1999 to be exact, according to the seller (who goes by the eBay name carhoarder)! Surprisingly, they have actually owned the car since 1975, so there’s a lot of history that goes with it. The car is currently in South Hackensack, New Jersey and is listed for sale here on eBay, where the thoroughness of the listing and the lack of a reserve already has bidding up to $12,600.


It’s pretty obvious that unless you love the “rat” look, this car will need some cosmetic refurbishment prior to putting it back on the road. That black fender in the top picture is said to be NOS, although why it was needed isn’t known. The seller has included some nice pictures and even took some of the small rust holes on the underside of the car.


Here’s one of the pictures they’ve included of the rust on the outside surfaces. Certainly nothing that can’t be fixed, but it’s nice that you are aware of it going in.


Here’s one of those underside shots. There’s enough heavy pitting on some of the cross members that I’d want to address it quickly, but the seller is correct in that there aren’t many holes, and what is there isn’t very big. So there’s hope!


Pontiac wasn’t exactly modest when they were advertising the 1970 GTO. Dubbed “The Humbler,” the wide-track brand felt that the car was “dazzling”, and delivered a “basso burble” from the optional performance exhaust. Can you imagine a car advertised like that now? I’d love to see it!


When I first saw the interior, I thought it wasn’t too bad, but then I started looking at what is either mold, mildew, or something worse on the steering wheel and on some of the other interior panels. Lots of heavy cleaning in order before you can determine what can and can’t be restored, refurbished or just reused. It’s nice to know that you would be doing this to a decked-out car, with air conditioning, power disc brakes, power steering and a limited slip differential.


Here we have the Pontiac 400 cubic inch V8. The seller tells us it does turn over, but won’t start at the present time (they suspect a tune up would have it running). I’m thinking that unless it was put away with the fuel drained, and there’s no sign of that, you are going to have quite a task ahead of you cleaning out the crud that will have accumulated. But perhaps that’s a task you are willing to take on for the privilege of driving “The Humbler?”

    Wow, 70 GTO convertibles were great looking. I tried to buy one years back but the guy would not sell and just let it weather away. Fortunately, it only got dry rot here in the soutwest. I have never seen an A/C compressor so rusted. Could this poor car have have sat in a swamp at one time?


  2. JW

    Had a 70 hard top with the 400 v8, actually I like the styling of my 2 67s and the 65 I sold because of stupidity than the 70. This one has been stored I feel in a damp garage somewhere. I also think there is more rust than the seller is showing.


  3. JoeR

    20,000 miles as per the listing….not original engine, so either 20,000 on the replacement engine or 120,000 on the vehicle.


  4. Scat Pack

    Car Guy, I have never seen an air filter element with that much rust.


  5. Fred

    This car is not a “Humbler”, or else that option would be listed on the build sheet.

    Only 223 +/- cars ever came with the Humbler exhaust option.

      As of now, it looks like it has a pair of Flowmasters.

    The seller also is selling a 1968 much better condition.


  7. Vince Habel

    The Humbler is a 455.

    This is showing signs of being under water, light flood. They rust from the inside out. Hence the rusty engine components. I bought a lightly flooded 78 Monte for parts and it displayed the same issues. Every bit of metal under every piece of plastic is probably rusted. They rust from the inside out.


  9. Tom Member

    Unless this car is “Christine’s GM Sister” and can fix herself, really don’t want any part of it !!! Yikes.


  10. Steve

    For every rusted spot you see, there are three hiding. It would be an awesome car, just a lot of work and $$$

    Rust would be a major concern. Here in NJ, we are gearing up for salt season, when winter storms bring ice and snow, and salt trucks try to combat the slick roads, leaving blankets of salt that kicks up under cars.
    As indicated, this car might have seen water. Anyone remember Hurricane Sandy?
    The car is currently in South Hackensack, but might have been stored closer to the Hackensack River.


  12. GTO MAN 455

    I have a 70 455 convertible its an awesome goat but not many made, if you get this for the right price its worth the build GRRRRRRRR


  13. Rustytech

    Why would anyone buy a car like this then stick it in storage for 18 years and not do anything with it. If it had been mine I would probably be divorced for abandonment by now for spending so much time in the garage!

    This is an excerpt copied from wiki…
    “A new and short-lived option for 1970 was the vacuum operated exhaust (VOE), which was vacuum actuated via an underdash lever marked “exhaust”. The VOE was designed to reduce exhaust backpressure and to increase power and performance, but it also substantially increased exhaust noise. The VOE option was offered from November 1969 to January 1970. Pontiac management was ordered to cancel the VOE option by GM’s upper management following a TV commercial for the GTO that aired during Super Bowl IV on CBS January 11, 1970. In that commercial, entitled the “Humbler”, which was broadcast only that one time, a young man pulled up in a new GTO to a drive-in restaurant with dramatic music and exhaust noise in the background, pulling the “exhaust” knob to activate the VOE and then left the drive-in after failing to find a street racing opponent. That particular commercial was also cancelled by order of GM management. Approximately 233 1970 GTOs were factory built with this rare option including 212 hardtop coupes and 21 convertbiles, all were “YS” 400ci 350 hp with either four-speed manual or Turbo Hydra-matic transmissions. This particular GTO in the commercial was “Palladium” silver with a black bucket interior. It was unusual in several respects as it also had the under-dash “Ram Air” knob just to the right of the VOE knob, and it sported “’69 Judge” stripes, as a few very-early ’70 GTOs could be ordered with. It also had a Turbo Hydra-matic transmission, remote mirror, Rally II wheels, A/C, hood tach, and a new-for-1970 Formula steering wheel.”

    Here is a link to a reproduction of the VOE exhaust that you can buy right now for your GTO.

    Really????? This has hurricane Sandys name written all over it. Rust issues are minor compared to electrical issues.
