Rarity claims are often meaningless without verifying evidence, and must sometimes be taken on face value. However, sources like Marti make such claims fairly easy to prove when the vehicle in question is a First Generation Mustang. The seller claims that only around forty examples of the 1966 GT Fastback were ordered wearing the paint shade found on this car, and, if confirmed, that makes it a very rare beast. Faulting its condition is seemingly impossible, while a selection of factory options enhances its desirability. I must say a big thank you to Barn Finder Curvette for spotting the GT listed here on Craigslist in Vancouver, British Columbia, Canada. It could be yours once you have handed the seller $59,000.

Some classics blend into the background, while others possess the “wow” factor. This Mustang falls neatly into the second category, courtesy of a repaint in its original shade of Signal Flare Red. The seller claims that the paint was applied around five years ago, stating that it is still flawless. There are certainly no visible problems in the supplied images, with the paint holding a phenomenal depth of color and shine, and the contrasting White stripes looking crisp and clean. The correct grille, fog lights, and the remaining trim are in as-new condition, and the glass is crystal clear. I can’t spot any evidence of rust, and the lack of surface corrosion in areas like the engine bay bodes well for potential buyers.

I have always aspired to own a ’66 GT Fastback, and this car falls short of my Wish List in one crucial area. My dream car would feature a K-Code 289 under the hood, whereas this GT features the less potent A-Code. However, with 225hp and 305 ft/lbs of torque at the driver’s disposal, the performance should still satisfy most potential buyers. The first owner focused on a relaxed driving experience, outfitting the Mustang with a three-speed automatic transmission, power steering, and power front disc brakes. It is unclear whether the vehicle is numbers-matching, although that may be the case if we read between the listing lines. The seller states that the engine has only clocked around 2,000 miles since receiving a rebuild, meaning that it is barely broken in.

The positive vibes continue inside this Mustang, with the car trimmed in Black vinyl. The first owner ticked the boxes on their Order Form beside the console, AM radio, and the ultra-desirable Rally-Pac gauges. The only visible aftermarket addition is the wrap, which I consider to be cheap insurance to preserve the wheel. Otherwise, this interior presents as spotlessly as the rest of the vehicle. I’m not sure if it qualifies as factory-fresh, but it doesn’t miss that mark by much if it isn’t.

Regardless of its potential rarity, there is much to like about this 1966 Ford Mustang GT Fastback. Its presentation is almost impossible to fault, and its mechanical health means that someone can enjoy this classic immediately. The only question it poses in my mind is whether it is numbers-matching, as that will impact its future investment potential. If it ticks that box and the paint shade claim is confirmed, this GT could be a winner. Are those thoughts enough to tempt you to pursue it further?
