Super-Rare 1970 Ford Mustang Boss 429 In ‘Pastel Blue’ Set To Auction

The 1969-’70 Ford Mustang Boss 429 is a rare, collectible bird in and of itself. A few more than 1,300 examples were ever built, with 500 or so being sold for the 1970 model year.

Of those, only 18 were shod in the same “Pastel Blue” shade as the car pictured above, and of those 18, just two were optioned with white interior trim. This is one of those two Ford Mustang Boss 429s.

A true collector might delight to know that this very Pastel Blue 1970 Ford Mustang Boss 429 is headed for the auction block this May, courtesy of Mecum Auctions‘ Minneapolis event. This car received a full Concours restoration as recently as 2008, carried out by Michigan Boss 429 specialist Martin Euler, and boasts a fully-rebuilt 429 cubic-inch V8 with a matching numbers 4-speed transmission and rear-end.

So, how did such a uniquely rare special-edition Ford Mustang ever come into being? According to the Mecum Auctions listing, the original owner was a 19 year-old girl whose father bought it for her new as a high school graduation present. Being a car enthusiast, the father was adamant that the car be a Ford Mustang Boss 429; the unique-taste paint and interior colors were up to her.

    I believe that I almost bought this exact car back in 1978 for 600 dollars! Pastel blue with a white/black interior. It was sitting on the lot at Packy Webb Ford in Glen Ellyn, one of my buddies that was a porter there called me and clued me in that the was “some bad assed Mustang with a monster motor on the lot”. I had the money, but the sales manager told me he would only sell it to me if my father agreed. I was offended because I was 18. Called dad, he shows up asking why do you need my permission, you have bought cars here before. The sales manager insisted that he drive the car first, then my dad can drive if we are still interested. He idled on to Roosevelt road in second gear without touching the gas, it sounded like two big rocks rolling down a hill in a garbage can, as soon as he was straight on the road he STOOD on the gas IT STARTS SCREAMING, about an eighth mile, power shifting thru three gears doing a burnout the whole time, a hole shot u turn in the middle of the street, three more gears and parking back in the same spot on the lot, all within less than 30 seconds, the salesman turned to my dad and asked, you think a kid should have this car? My dad smiled, shook his hand and said, thanks for putting his life ahead of your profit, when I drove by the next day it was gone. until he passed away, every car he bought was from Packy Webb. Every time I see a 70, I am 18 again.

      Had almost the exact same thing happen to me with an R Code 1969 Mach 1. I was 17 and drooling. 1987 and they were asking $6700 and it was perfect. It didn’t sit on the lot long either.

        This was 1978, 600 bucks!!!!
        I realize now that if I had gotten it, both it and I would have been history in a few hours, looking back, it’s a great memory, but the sales guy and my dad were right
