The Boss 429 was a special Ford Mustang model only offered in 1969 and 1970. Production numbers were low, and fewer than 500 were built in 1970. Its 429 cubic inch V8 was conservatively rated at 375 horsepower, and the one in the seller’s car is said to be stock, although rebuilt. A restoration of sorts seems to have been done on this 1970 vehicle, but it’s not 100% finished. Located in Hunlock Creek, Pennsylvania, this car’s VIN decodes as the real thing, and it’s available here on eBay for…….drum roll……$200,000.
Ford’s successful Mustang was experiencing a decline in sales in the late 1960s, due mostly to a flood of competition and the market becoming saturated. They rolled out three new models in 1969 – the Mach 1, Boss 302, and Boss 429. The latter was the baddest Mustang before or since and probably cost its owners a small fortune when it came to insurance premiums (which were on the rise for muscle cars). The Boss 429 helped introduce the engine to the NASCAR world, and in the two years, just 1,358 copies were sold for street use.
Considering the seller’s asking price, the description that encompasses a decent selection of photos is minimal. We’re told the seller has the alternator, but not the bracket. And perhaps the shifter and clutch linkage isn’t complete for the 4-speed manual transmission. Though the car is said to have 56,000 miles, the engine is freshly rebuilt and still in the break-in period. No mods were made to the 429, which we assume is numbers-matching from the paperwork provided.
Both the tranny and rear end have also been rebuilt. And the seats have been redone. The paint looks new, but it doesn’t seem to have a great deal of luster (or is it me?). If you’re looking for a rare muscle car and have $200k to spend, is this the one you would go after?
Title shown indicates M code 351 four barrel.
then he’s selling a fake that should be obvious to anyone with $200k to spend, but on the other hand, a fool and his money…
It appears the title is not for the Boss 429. Boss 429s are always manufactured in Dearborn not in Metuchen NJ
Typo? It’s a real boss 9 “Z” is in the car. If the title is wrong the owner should fix that. If not title service or having it inspected by the dmv
I have the ability, and I am a Mustang fan, but the Boss 429 is not a car I would choose. My BMW M3 was a homologation special, which this was also, but the M3 is genuinely fun to drive on the street. These were not.
The 1969–1970 Ford Mustang Boss 429 struggled with poor low-end torque, severe engine overheating, and front-heavy handling due to its massive, tightly packed NASCAR-derived engine. Street versions were choked by restrictive emissions equipment, small carburetors, and log exhaust manifolds, resulting in disappointing performance for its “Boss” moniker, often requiring significant owner modification to reach its 500+ hp potential.
More than anything, the value of the 429 Boss is in its scarcity. As to which car I’d rather drive, the M3 all day long.
comparing apples to oranges with this claim. Two completely different categories.
While everything that is said is true, these cars will never be driven on the road again. At least not with any intent.
I will look at a real car over a nonsense car any day. If I want a car that is great to drive I’ll take my blue on blue 05 NSX out. If I wand a great old car that actually means something I’ll take my 66 Shelby out. Yeah there are fun cars out there but then there are real cars. There is always my boss 302 Laguna Seca or my 70 boss 302. It is soooo much more rewarding to drive a boss9 then a newer car.
For the asking price the car should be better, the paint is not great, or is it just the picture? It should be completely perfect, not needing anything but your ass in the seat. Also, if It’s a true boss and I were selling I would
D take it to one of the auctions.
I feel that this was a restoration done by an individual, not a shop. He probably has been working on it for years and something happened that now he has to sell before it is finished.
He won’t get 200K for it, but that’s what the car is worth to him in time / effort / sentimentality, which hardly ever pay off.
With a car like this i would think a little more car would be given on the paint job there is over spray on the tires. For this kind of money it just looks like the paint was a quick and rushed job. For an asking price of almost a quarter million dollars better pictures and wiping the over spray off the tires would make a big difference.
They’re kidding with that price, right? I guess he figures if he finds a sucker, he won’t have to keep selling truck parts.
The seller is dreaming, or watched too many auctions. Many body panels do not line up.
The sellers website in interesting. It showcases the primary focus of their business.

Sure does need a lot of TLC for 200k. And the paint overspray on the tires does not inspire confidence that much attention to detail was given during the repaint. Add things like the poor fitting window trim or the half inch gap in the door and quarter windows or the funky fit of the mirror in the door housing…I could go on, but I think everyone gets the point. And that was noticed just from the BF pics, I didn’t even click the link. I’d look this car over thoroughly as I am sure more issues will be found.
At that price, finish the work! Especially the engine break-in, leaving the possibility of all to common camshaft failure to the buyer is not acceptable. Not to mention the poor attention to details like hood and other items others have stated.
I could tell this was a clone looking at the first picture. I would much rather spend my money on a Boss 302. They are more exciting to drive and easier to maintain. These 429’s may be rare, but there’s a reason for that and why so many of them have low miles. They were never in the discussion of being a practical muscle car and will melt you sitting in traffic!
Title VIN does not match to the car VIN… somethings is’nt right with this one…
Where are the hood locks?
Thought I was looking through Barnfinds this morning not the funny papers!
Title VIN decodes as a Mustang with sport roof, 351 4V Cleveland engine. At best, this is a “Tribute” car.
At least paint it all the same color.
Yikes! The dash VIN has been restamped! Can you say FELONY??
FAR away from this one! Looks like it doesn’t have the correct rear end set up.
On May 3, 2022 an original, bone stock ’70 Boss 429 with less than 20000 actual miles sold at auction in Nebraska for $442000
70 Boss 429 never came in yellow for starters so why would you diminish the value by ever painting it yellow.. This car screams “fake” from every angle. Certainly NOT a $200,000 car by any measure.
And to ask $200k without offering a Marti report for any FOMOCO product is truly not cool.
Picture 12 of 41 shows a Marti report, as is rarely mentioned but should be remembered, never assume the presence of documentation authenticates a car. Authentication is more involved than looking at a piece of paper.
Steve R
There is a Marti Report shown, and it matches the VIN on the car, but does not match the VIN on the title.
If it has a Z it’s real
So it has a Z in the vin. I guess it must must authentic…??!? IT’S A FAKE!! Vin has been poorly restamped!
Perfect REAL Boss 9s sell for maybe $350,000 today. In reality, they were terrible street cars with a carburetor that was far too small for those giant cylinder heads. I believe they came stock with a 735 cfm Autolite. This car is far from 200K. Dumb people will bid on it.
never saw 1in this color. where is the plate with the KK number. i smell a rat. poor quality all around. yeah, it’s got the motor and a Marti report but i am not convinced it’s real. too many flags in my view
For all of those on here saying the price is too high, if it is a real Boss 429 (which it doesn’t appear to be to me), $200K would be more than fair. Boss 429 project cars sell in that range, not assembled, running cars.
I looked at three very rough 69 Boss 9’s late last year for a customer. All of them were in the $200K-$225K range, and all needed full restorations, were missing a lot of expensive parts (which this car appears to have), and none of them were running. The very rusty Boss they settled on came with just a numbers matching bare block and a crank under the hood. A set of heads set me back over $10K, and I paid another $7000 for a correct dated Holley carb. This car could be worth close to $200K just for the Boss 429 parts if they’re real.
To Donnie MacInnis, the Boss 429’s did not come with hood pins.
To JR, this car is not yellow, it’s Grabber Orange, one of the 5 colors the 70 Boss 429 was available in.
To George Matter, Boss 429’s came with a unique Holley 4647, that also had a Ford part number on it, not an Autolite carb.
To hairyolds68, as I said above the color on this car is Grabber Orange, a correct color for 70 Boss 429’s. As far as the “plate” with the KK number, these cars never had a plate on them. The KK number was found on a label glued to the driver’s door below the factory data plate. It may or may not be on this car, we’d need to see a picture of the driver’s door open to know. But since new labels are readily available from ECS, a KK label doesn’t really prove anything.
WOW I think there is an extra zero in the price!! I agree with most all comments here.
