Chevrolet offered three versions of the same engine, starting with a 340-horsepower configuration sporting a 10.1:1 compression ratio. The carmaker upgraded the more powerful 400-horsepower sibling to an 11.0:1 compression ratio and an aluminum intake.

The 425-horsepower unit was the icing on the cake, with an aluminum intake and two four-barrel carburetors, fitting an Impala SS like a glove.

The 1963 Impala SS posted on eBay by seller amov8000 proves the SuperSport tags and the big-block monster were a match made in heaven. And thanks to owners who knew what they were doing, the car still flexes a mesmerizing condition you can’t find elsewhere.

This Impala flexes the magic package: all-original, complete, unrestored, unmolested, and low mileage. The seller says the Impala attended several car shows, so I guess it spent most of the time in a garage, preparing for the next venue.

If this is the case, its condition makes perfect sense. The SS is spotless inside and outside, and everything is working correctly. All SS tags are in place, and the white finish is flawless.

As a “real original survivor” (the seller’s own words), this Impala doesn’t need anything other than a new home. The owner says the car is ready to become a daily driver, though it undoubtedly deserves a place in someone’s collection, with occasional weekend drives or trips to car shows.

The 1963 Impala SS was a small rocket on wheels when fitted with the 409 V8, but considering the car spent most of its time inside, the odometer reading also makes it a low-mile surprise. The vehicle has just 26,000 miles (close to 42,000 km) on the clock – most of the miles result from the car heading to car shows and then going back home.

The auction is already underway, but as expected, this Impala SS won’t sell for cheap. As a rare survivor with everything in tip-top shape, the car sells at auction with a hefty starting price. Interested buyers must be willing to pay at least $25,000 for the vehicle, but the owner also enabled a reserve. In other words, the seller expects to get much more than that, and while no information is available on the reserve’s value, I believe it’s close to double the starting auction price. This Impala could, therefore, be available for anyone willing to pay $50,000, which looks like a fair price for an all-original, unmolested, and unrestored low-mile survivor.

The owner keeps the vehicle away from rain and sunlight in Greenville, South Carolina. Theoretically, because everything is in working condition, you can drive the car back home without any mechanical fixes beforehand
