Mileage claims are one of the slippery slopes of the classic world. It is easy to state that a particular vehicle has an extraordinarily low odometer reading. However, proof is required if the claim is to be treated at anything more than face value. That brings us to this 1970 Ford Mustang Grande. It presents exceptionally well for its age, and after spending its life with the same family, the time has come for it to head to greener pastures. The seller claims it has a genuine 21,000 miles on the clock, so why not take a close look to see what you think?

While it wasn’t “panic stations” at Ford in 1970, it was becoming clear that increased competition from General Motors and Chrysler as well as its own market saturation was having an impact on Mustang sales. This was the first year since 1964 that the sales total had dropped below 200,000 cars, with 190,727 buyers taking one home. The company introduced the more luxurious Grande variant the previous year, and 13,581 people splashed the cash on one in 1970. This is one of those cars, and the initial impression is positive. The seller claims it has been part of the same family since Day One, and the car’s overall condition suggests they really loved their classic pony car. The Medium Lime Metallic paint shines impressively, with only a few minor chips and marks that most would consider acceptable on a genuine survivor. The panels are as straight as an arrow, and the gaps are tight and consistent. The vinyl top is exceptional, with no evidence of deterioration or developing bubbles. This is a First Generation Mustang, which will lead many to raise the question of potential rust issues. However, this is a dry-climate survivor, which is extremely good news. The exterior is spotlessly clean, while the underside shots reveal no problems with the floors, rails, or torque boxes. The trim is free from significant issues or deterioration, and there are no visible problems with the tinted glass.

Ford continued its trend of offering buyers an entry-level six under the hood of 1970 Mustangs, but this car’s first owner teamed the 302ci V8 with a three-speed automatic transmission and power assistance for the steering and front disc brakes. The 302 wasn’t the most powerful weapon in the Mustang’s armory, but it delivered 220hp and 300 ft/lbs of torque. That brings us to a fascinating point to ponder and reveals the impact additional weight can have on vehicle performance The Grande brought a slice of luxury to the Mustang range, but it came at a cost. While a base model with the same mechanical configuration will tip the scales at 3,075 lbs, this Grande pushes that figure to 3,186 lbs courtesy of additional sound-deadening material and other changes that formed part of the package. Both cars could achieve the same top speed, but the Grande took 16.6 seconds to cover the ¼-mile compared to the more spartan model’s ET of 16.4 seconds. That isn’t a lot, but anyone who has competed in motorsport will confirm that every fraction of a second counts. Okay, it’s crunch time with this classic, and the seller’s claim that it has a genuine 21,400 miles on its odometer will undoubtedly ignite debate. They mention the presence of a Marti Report, but no documentary evidence supporting their claim. The car’s overall condition makes it plausible, but that doesn’t constitute iron-clad proof. However, the winning bidder will slip behind the wheel of a vehicle that is a turnkey classic. It runs and drives perfectly, allowing the opportunity for someone to fly in and drive this baby home.

If this Mustang is all that the seller claims, its interior is particularly noteworthy. There is no evidence of wear or damage on any of its Ivy cloth and vinyl upholstered surfaces, the carpet is in good condition, and there are no visible problems with the dash, pad, console, or plastic. The lower steering column shroud has developed a strange “aged” look, which seems out of character with the rest of the trim. I am unsurprised that given its location it scores air conditioning, but it appears the factory AM radio has made way for a retro-style stereo. Otherwise, the interior is unmolested.

It will be fascinating to gauge your feedback on this 1970 Mustang Grande, and whether you believe the mileage claim is valid. The car’s overall condition and presentation suggest it is possible, although I have seen some remarkable classics that make a positive impact after the odometer has rolled over. The seller has listed this Grande here on eBay in Dallas, Texas. It has generated reasonable interest, with fourteen bids pushing the price to $10,600. That figure is below the reserve but demonstrates that there are enthusiasts who are willing to roll the dice. Would you do the same?
