<P> Unfortunately sales started to drop off for the 1970 Boss 429 Mustangs and with higher production costs, gas costs, and other internal Ford problems, it was decided that 1970 would be the last year of the Boss 429 . </P> <P> In present day, these cars are highly sought after . As of 2008, auctions on eBay and at Barrett - Jackson have brought bids of over $375,000 . In 2013 a black 1969 Ford Mustang Boss 429 Fastback (unrestored) sold for $417,000 at Mecum Auctions in Kissimmee, Florida . In 2016 a restored black 1969 Boss 429 sold for $500,000 at a Barrett - Jackson auction in Palm Beach, Florida . </P> <P> In 1969 there were 859 Boss 429s made by Ford Motor Company, two of which were Cougars for the Lincoln / Mercury Race Division . There were five different colors available in 1969 (Raven Black, Wimbledon White, Royal Maroon, Candy apple Red, and Black Jade), and the only color for the interior was black . The fully functional hood scoop was the same color as the car, and noticeably larger than anything else offered on any Ford product at the time, with the exception of the two Boss 429 Cougars . This scoop would carry over to the 1970 model year but would be painted black on all cars . To this day, it is the largest factory hood scoop ever installed on a factory produced Mustang . All these cars were a manual transmission, and there was no air conditioning available due to the size of the engine . Though not originally offered as an option, it is common to add a spoiler and window louvers commonly seen on 1969--1970 Mach 1's and Boss 302's . Some early cars were known as "S" code cars and as such had a slightly different engine . These cars had magnesium valve covers, NASCAR style forged internals, nearly no smog or emissions equipment and are said to be more powerful than the later "T" and "A" code engines which had the emissions related equipment to satisfy government regulations . The engines in some cases were removed from the cars for use in other applications such as tractor pulling, due to the extreme torque and horsepower the engine was capable of producing . </P> <P> In 1970 there were 499 Boss 429s made by Ford Motor Company . There were five new exterior colors (Grabber Orange, Grabber Green, Grabber Blue, Calypso Coral, and Pastel Blue) and the interior was available in black or white and black . The hood scoops for this year were all painted matte black regardless of the color of the car . These cars also had a manual transmission and no AC was available, again due to the size of the engine . The Hurst Shifter was also standard equipment for this year . A dealer - installed option of a six - pack intake and carburetors was also made available; however very few of these were sold . </P>
