There's a good chance you've probably never heard of the Fisker Latigo. Henrik Fisker is best known for penning the designs of the Aston Martin DB9 and EVs like the Karma Revero and the new EMotion, but back in 2006 he tried to revive coachbuilding with the Latigo. Based on the E63 BMW 6-Series and designed by Henrik Fisker, the initial plan was to build 150 examples but production was cancelled after the prototype and one production car was developed. And now that one rare production car is up for sale on Bring a Trailer.

Mechanically, the Fisker Latigo is based on the 2006 BMW M6, and features a rebuilt 5.0-liter V10, tuned by BMW tuner RD Sport to produce 665 horsepower, and a seven-speed sequential manual transmission. The only customer Latigo ever built is finished in Titanium Silver Metallic and features a bespoke leather interior an Alcantara headliner and rear package shelf, and billet aluminum accents, though the sales listing notes that there is some outer bolster wear on the driver's seat, while the rear window and Alcantara shelf were replaced in 2014. The steering wheel is sourced from the E63 BMW but has been recovered and features a Fisker logo.

A badge on the engine cover also displays the chassis number and Fisker's signature which still lists the car as "#001 of 150" when the remaining 149 models were never produced. Over 10 years ago, the Latigo will have set you back around $216,000 – and that's excluding the cost of the M6 donor car adding another $100,000 to the price. The car for sale only has 22,850 miles on the clock, but the current bid is only $37,000 at the time of writing so this could be a good opportunity to own one of Fisker's lesser-known models that's secretly a BMW M6 in disguise.
