1970 Boss 429, Originally a Grabber Green car

A true and real Boss 429.  Not a clone or a fake.  1 of 500 real 1970 Boss 429's.

Originally a very rare Grabber Green (1 of 52) with black interior (1 of 43) car.  Currently Midnight Blue.  

No rust ever.  Not been tubbed or cut up.  

Still wears its original Boss 429 rolled-lip fenders.  Original unmodified Boss 429 Unique Shock Towers. Original Battery Tray in Trunk. etc.

Highly professional and custom engineered high dollar upgrades.  Over 750 HP motor only. over 900 with NOS.  

Yet so well engineered and tuned. it is a street car and never gets over 180 degrees.

A performance enthusiast's dream of high end exotic parts and internals.  

Not an NOS paint daub guru "purist's" dream as it sits. but one hell of a ride and a real deal Boss 429 that you can drive!

This is an original Boss 429 with about as many steroids as you could pump in to it.

Full VIN and KK # will be provided only to the winner.

This car has a ton of documentation with it. including the original invoice. full Marti report. prior ownership details. magazine articles. and info on the various upgrades.  A ton of money. design. engineering. trial and error / back to the drawing board rework went in to making this car run right as a reliable high horsepower beast.  The heads alone have hundreds of hours in them.

The paint is nice quality for a driver. but does have its imperfections.  I would imagine the new owner will return it to its rare original Grabber Green hue in due time.  You can see in the paint nicks in the wheel wells. the original Grabber Green paint showing underneath.

As you can see. the interior has been modified. but luckily for those of you wanting a more original look. most all of those pieces are readily available and cheap as they interchange with the lower model Mustangs.

The car currently has a louvered fiberglass hood on it.  The trunk lid was also louvered.  I have the original Boss hood and hood scoop that will go with the car (not photo'd).  Those are the only additional original parts I have and that go with the car.

Marti Report included so you can see how this car was originally optioned when it was factory fresh.    

$500. 00 Deposit required within 24 hours.   Full payment within 3 days of close of auction.

Transportation the responsibility of the buyer.  

International buyers considered.

No Trades.

Please don't send me silly lowball offers.  I do not "need" to sell the car.  

Only if you are a serious buyer. email me with questions if you have any after you read the entire listing. view the pics in detail. etc.

No questions like - Do you have the original blah blah?. Why was blah blah modified?  etc.  I won't bother to answer questions that are clearly listed in the auction description and pics.  It is what it is. an ultra rare original Boss 429 car that has obviously been modified and driven over the years.  

The car is wicked. the modifications would cost $50k plus to make. although I know not to the tastes of the thoroughbred purists out there.  

No time for tire kickers. droolers. wanna be joy riders. know it alls that want to pick apart the originality of the car. etc.  It is what it is. 1 of 500 that were produced.  It would be easy this summer to be put back to Grabber Green. and change over to a more stockish interior and exterior appearance if you so desire.  The drivetrain is so well sorted and full of reliable high end rare bits. I would personally never return the drivetrain aspect of it back to stock. but would enjoy it as a driver.

The sound of this car sitting there idling is just more awesome than I can express in words.

Wire Transfer is only method of payment for international buyers who must have their own broker.
