Aston Martin Zagato replica with a eBay Buy It Now price of $2.4 million.

For all of the attention to detail that went into this beautiful, custom-built 1960 DB4GT Zagato, it almost seems a shame to call the Aston Martin a "replica." But because it started out as a non-Zagato coupe (only twenty originals were built) and is now powered by a supercharged inline six sourced from a 1997 DB7, it must wear the term on its sleeve. What's most astounding about this eBay find, however, isn't the fact that it's claimed to have been built from the ground up or that its original title might have been a duplicate, but the $2.4 million Buy It Now price.

The seller claims he has nearly 40 years of title and ownership history, including all receipts for the $1 million-plus Zagato build, and the big names involved in the project - such as renowned coachbuilder Clive Smart - along with extensive photo documentation go a long way to convince us of the build's authenticity. Still, the seller claims that a discrepancy with the Vehicle Identification Number forced the builders to register the car with a new VIN plate, so, if you're somehow in the market for this car, shop with discretion.

The seller's statement about the car's identification crisis is this: "We have learned that record keeping in those early days at Aston was not efficient and duplicate VIN plates were not unheard of. We believe this car to be the genuine article, but we know it is 100-percent Aston Martin."

Feel free to check out the gallery we've included of the car, but be sure to visit the eBay page to pore over the extensive photo documentation we're talking about - there's something here for every type of car enthusiast, even if it's just to gaze at the replica's beautiful lines.
