Although it had become bigger and heavier during its production life, many enthusiasts believe that cars like this 1970 Mach 1 represent the First Generation Mustang at the peak of its power. The increased dimensions allowed Ford to shoehorn larger and more potent powerplants under the hood, creating cars with genuine performance credentials demanding respect. Such is the case with our feature car, which features the legendary 428 Cobra Jet V8. It has generated significant interest since the seller listed the Mach 1 here on eBay in Mercer Island, Washington. Frantic bidding has pushed the price to $50,001, but with the end rapidly drawing near, interested parties may need to act fast if they want to give it a new home.

There is a lot to like about this Mach 1, and its overall presentation is a good starting point. Its original owner ordered it in striking Medium Bright Blue Metallic, a shade guaranteed to draw crowds. The Black stripes and decals add a muscular contrast, and the lack of flaws and defects might indicate the car has received a refresh at some point. The panels are as straight as an arrow, while the underside shot confirms this is a rock-solid classic with no rust to cause sleepless nights. The spoilers are intact, the trim and chrome are in good order, and there are no glass issues. The Mach 1 rolls on Magnum 500 wheels, and only those and the “Shaker” scoop hint there could be more to this Mustang than meets the eye.

Buyers could order their 1970 Mach 1 with a 351ci V8 as the entry-level engine. It provided respectable performance, but some chose to push the envelope with a powerplant that offered significantly more power. That is where the 428 Cobra Jet entered the picture, which we find occupying this classic’s engine bay. It generates an “official” 335hp and 440 ft/lbs of torque, which many knowledgeable individuals believe are conservative figures. The power feeds to a four-speed manual transmission, while power assistance for the steering and front disc brakes should lighten the driver’s load. Is it fast? As a point of comparison, the entry-level 351 produces a ¼-mile ET of 16.1 seconds. This car slashes that figure to 14.7 seconds, and keeping the pedal to the metal will reward the driver with a top speed of 131mph. The seller doesn’t specifically say the car is numbers-matching. However, that appears to be the suggestion. It has a genuine 55,000 miles on the clock and is ready to provide its new owner with immediate motoring pleasure.

The theme of spotless presentation continues inside this Mustang, with its interior trimmed in Black vinyl. There is nothing rating criticism, with the upholstered surfaces spotless, and the carpet and headliner equally impressive. The faux woodgrain hasn’t deteriorated, and the rim-blow wheel has avoided the typical cracking issues. The car retains its original Hurst shifter and AM/FM radio, and there are no aftermarket additions.

It can sometimes be challenging to determine whether a classic is genuinely desirable, but this 1970 Mustang Mach 1 leaves no doubt. It has attracted fifty-nine bids, and with the auction drawing to a close, the action might intensify. This car will never be considered affordable, but it could be a rock-solid long-term investment. Hmm, an investment-grade classic that offers an exhilarating driving experience? I can’t think of anything wrong with that scenario. Can you?
