§ V.02What moves a car within the band
Within that band, coupe cars are the most frequently traded body style in this set (100 of 259 sales), and manual cars account for 215 of them. Condition, originality and documented history move a car further than any single specification, which is why the middle half of the range is wide.
The spread by variant, printed in full above, is usually wider than the spread by year: a coupe at $89,650 and a fastback at $84,150 are not the same market, and a single median that mixes them describes neither.

The middle half of those 259 sales fell between $70,200 and $230,500 (the typical range), and the full range after cleaning was $26,400 to $605,000.
What affects the price of a 1969–1970 Ford Mustang Boss 302 and Boss 429?
Model year: by year, medians run from $85,000 for 1970 (177 sales) to $227,750 for 1969 (82 sales).
Body style: a coupe holds a median of $89,650 on 100 sales, against $84,150 on 74 for a fastback.
Condition, originality and documented history move a car further than any single specification, which is why the middle half of sales spans $70,200 to $230,500.
Is the Ford Mustang Boss 302 and Boss 429 1969-1970 going up or down in value?
Down. The 29 sales in the 12 months to 3 November 2026 had a median of $105,000, against $118,250 on 26 sales in the 12 months before, a fall of 11.2%. That compares whichever cars came to auction in each year, not the same cars sold twice, so read it as the direction of the market rather than a rate of appreciation.
How many Ford Mustang Boss 302 and Boss 429 sales is that based on?
259 completed auction sales, from January 2016 to 30 October 2026. The table above lists the 15 most recent, each linked to its auction record. The figures were last rebuilt on 3 November 2026.
What is the difference between the typical range and the full range?
The typical range is $70,200 to $230,500: half of all 259 sales fell inside it. The full range is $26,400 to $605,000, the cheapest and dearest sale that survived cleaning. The full range is set by outliers, so it is a boundary rather than a guide to what most cars bring.
Which body style holds its value best?
On this set, coupe is the most frequently sold at 100 sales with a median of $89,650. The highest median among body styles is coupe at $89,650, though it rests on fewer sales. Each variant's median and count are in the table above.
Do manual or automatic cars sell for more?
In this set, manual cars account for 215 of 259 sales. Too few cars of the other transmission type sold to publish a comparison, so this page does not make one.
Does mileage change the value?
Mileage is recorded for part of this set, not all of it, so it is not used to adjust the median. It is shown in the sales table wherever the auction record carries it, and you can see the effect directly by comparing rows.
How current is this figure?
Data as of . The figures are rebuilt from completed sales on a schedule, and the date above is the date of the last rebuild, not the date this page was loaded.
§ V.07Method and sources
What these figures are. Every number on this page is computed from completed auction sales of Ford Mustang Boss 302 and Boss 429 cars built between 1969 and 1970. The median is the 50th percentile of the sale prices; the typical range is the 25th to 75th percentile; the full range is the lowest and highest sale that survived cleaning. Percentiles are linearly interpolated on the sorted prices.
What is excluded. Asking prices, reserve-not-met results, withdrawn lots and unsold cars are not prices and are not counted. Parts, memorabilia, literature, scale models and other non-vehicle lots are excluded. Sales not made in US dollars are excluded, so these figures describe the dollar market. Duplicate records are removed. Sales below a plausibility floor (5% of the median) and above a ceiling (10× the median) are set aside, because a $22 "911" is a data error rather than a cheap car.
What it is not. This is not an appraisal or an inspection, and it does not predict what any particular car will bring. Two cars built the same year can differ by more than the whole typical range on condition, originality, documentation and provenance.
The set. 259 sales from January 2016 to 30 October 2026, drawn from 10 auction sources, principally Barrett-Jackson (147), Bring a Trailer (83), RM Sotheby's (11), Mecum (4), Bonhams (3), Broad Arrow (3), Gooding (3), Acc (2), Autohunter (2), Hagerty (1). Data as of .
