This triple black 1971 Dodge Challenger R/T carries the paperwork of Mr. Norm’s Grand-Spaulding Dodge, the Chicago dealership famous for building factory Hemi muscle cars regular buyers could special-order off the showroom floor. Under the hood sits a 425-horsepower 426 Hemi, built in the final model year before compression ratios and horsepower ratings changed for good. Mopar fans in the comments call it a dream car outright. Watch to see why documentation matters as much as horsepower on a car like this.
