1969-1978 Ford Mustang Mach 1: A Comprehensive Guide On Features, Specs, And Pricing

Ford came out with the Mustang in 1964½ as a car to attract young people to the brand. While the original pony car was certainly fun to drive, it had modest performance. Around the same time, the classic era of muscle cars was beginning and Chevrolet unleashed the Camaro, while Plymouth let loose the Barracuda, both of which had scary-fast engine options. In an effort to keep up with the power race, Ford developed several performance packages, like the GT and Boss series cars. Then, in 1969, they came up with the Mach 1, which was so successful, that all other packages were retired.

Available from 1969 until 1978, the Mustang Mach 1 package was the baddest of the bad for each of the model years. It actually encompasses three distinct body styles and two and a half generations. Initially, it was offered on first-gen Mustang SportsRoof fastbacks in ’69 and ’70. Then, from 1971 to 1973, when the first generation Mustangs got a longer, sleeker body style, the Mach 1 was again available on the SportsRoof versions. Finally, during the Mustang II era of the second-gen from 1974-1978, a much less powerful Mach 1 actually outsold the ’69-’73 versions by a wide margin.

Over the course of the Mach 1 package, dozens of engines were available from a 170cu V-6 to the mighty 429 Super Cobra Jet V-8. Though a ’69 and a ’78 are radically different vehicles, all original-run Mach 1s are united by the bloodline of the legendary Ford performance package. The Mach 1 would make some brief reappearances in the new millennium, but there’s nothing like the classics. Those ’69 to ’78 Mach 1s have become some of the most collectible cars in the Mustang’s storied history.

This guide provides comprehensive information provided by the manufacturer (Ford) sourced additional data for maintenance costs (CarEdge, RepairPal), reliability (Carsurvey.org), and average prices (Hagerty Valuation Tool, Classic.com).

Maintenance And Repairs

RepairPal says the average yearly repair cost for a Ford Mustang runs $709, but that’s for a 2022 model, not a classic. CarEdge reports that the average cost of repairs and maintenance for a Mustang in the first ten years is $7,093, with a 20.79 percent chance of a major repair in that time. This, again, is not exactly related to Mach 1s from the late ’60s and most of the ’70s, but YourMechanic states that Mustangs from any year, including first and second-gen cars, can expect repair costs between $105 to $4,530, averaging $335.

Most Common Ford Mustang Problems Reported

• Brake replacement
• Wheel bearing replacement
• Headlight replacement
• Brake light switch replacement
• Ball joint replacement

1969 to 1970 Mustang Mach 1s were built solid and will probably run forever with routine maintenance. The quality control of the Mustang IIs, especially in the late ’70s was less than desirable so the ’74-’78 Mach 1s probably need a lot more work. The good news is almost anything on a classic Mustang is easily replaceable and, because they made so many, parts are easy to find.

Repairs And Pricing Info

Generally speaking, most people with a classic Mustang do a lot of the mechanical work themselves, so repair costs are limited to parts. A major portion of the bill from a garage is for labor, especially if it involves pulling the transmission or engine. Luckily, most problems with a classic are fixable by home mechanics.

Recalls And Safety Investigations

There have actually been 21 NHTSA recalls of Ford Mustangs from the 1969 through 1978 model years. Nothing terribly major and almost all of them involve improperly installed parts, rather than faulty equipment or poor design. There is certainly nothing along the lines of the 1.5 million Ford Pintos that were recalled because they exploded in rear-collision accidents.

Reliability, Running Costs, And Expected Mileage

Websites like J.D. Power and Edmunds do not have reliability ratings on cars as old as the ’69-’78 Mustang Mach 1, but CarSurvey.org has a few relevant owner reviews. Thankfully, some of these reviews are actually for a Mustang with the Mach 1 performance package.

Reliability Rating: 10/10

Two 1973 Mustang owners provided reliability scores on Carsurvey.org, totaling the average reliability to 10 out of 10:

Both owners own a 1973 Mustang with a 351ci Cleveland V-8, which was the most powerful engine available that year. One owner has a proper Mach 1 and the other has a coupe that he or she refers to as “Eleanor” after the famous car from the Gone in 60 Seconds movie. Both have restored these cars and couldn’t be more pleased with the performance and reliability.

Running Costs: 3/10

One 1973 Mustang owner provided running costs scores on Carsurvey.org, totaling the average expense rating to 3 out of 10:

Only one reviewer gave a running costs score, and it was low because 1973 V-8s were gas-guzzlers. That owner commented that the “gas mileage sucks” on the 1973 Mach 1 and noted that it has to use the highest premium gas or the engine pings. The owner also stated that the car gets a combined 13 miles to the gallon.

Highest Miles Reported: 119,000

Two 1973 Mustang owners provided the highest miles reported scores on Carsurvey.org, totaling an average of 119,000 miles.

All the reviews for the 1973 Mustang were overwhelmingly positive with owners professing their love. One reviewer noted that the longer body style of the ’73 was not everyone’s favorite, but that he or she was totally into it. Several owners noted that they had picked these cars up for cheap prices, with one stating it is, “an underrated bargain of a muscle car.”

Pricing And Values

Valuation Highlights

These Hagerty Valuation Tool prices are for a 1969 Mustang Mach 1 with a 351cu V-8. Classic.com, which tracks auction sales for the previous five years, sets the average price for a ’69 Ford Mustang of any trim at $97,130, with the lowest sale being $2,200 and the top going for $605,000. The biggest sellers are the Boss 429s, but presumably, a Mach 1 with that same engine would be just as valuable.

What To Look For Before Buying

Covering the entire original run of Mustang with the Mach 1 performance package is very broad and encompasses several drastically different cars. Before shopping for one, choosing a generation is a must because prices vary wildly from affordable to astronomical. ’69 and ’70 Mach 1s are going to be six-figure rides, while later models will be in anyone’s budget.

Originality Of The Vehicle

The absolute first thing to check out on a Mach 1 is if it is legitimately a Mach 1. Not so much on the Mustang II versions, but definitely with the first-gens, many people have converted Plain Jane Mustangs into Mach 1 replicas. On the first-gen Mach 1s, take a look at the door data plate. If it doesn’t have the body style code 63C, it’s a fake.

What’s Under The Hood

Matching numbers Ford cars may not be as important as they are with Mopars, but they can still be more valuable. If the Mach 1 is an investment, make sure the car has the engine and transmission it left the factory floor with. At the top level, with a 428 or 429 Mach 1, an original engine could mean a $100,000 difference from one with a crate replacement.

Watch Out For Corrosion

As with all classic cars, rust is the most important thing to look for, especially if it isn’t a California car. Typical areas to look for signs of rust on a Mustang include around the wheel wells, the bottom of the fenders, door sills, and the floorboard, under the battery. Get under the car to look for holes and make sure the engine mounts aren’t rotted out. Also, a car can look great from the outside, but may be a painted-over Bondo nightmare, so bring a magnet and see if it sticks.

Is It Worth Buying A Ford Mustang Mach 1?

A first-gen ’69 or ’70 Ford Mustang Mach 1 is one of the coolest rides of the classic muscle car era and any collector would salivate to own one. They are, however, quite expensive and probably wouldn’t be anyone’s daily driver. If money is no object, one should definitely be picked up, but it’s not going to be as viscerally enjoyed as something less rare. As an investment, it’s a can’t-miss opportunity, because it will never go down in value.

In terms of a car that can be driven, a ’71 – ’73 Mach one is the perfect sleeper pick. They still looked cool and had fast engines, plus they could be picked up for reasonable prices. A perfectly restored, matching numbers ’72 Mach 1 with a 351 and four-speed sold on Bring a Trailer for $49,000 in 2024, which is better than a similar new performance Mustang price. As for the ’74 through ’78 Mach 1s, they could make for some great project cars. For less than $25,000 a Mustang II Mach 1 can be had, restored, and fitted with a Coyote crate engine for some serious retro-modded classic fun.
