Carmakers and design studios occasionally come up with one-off automobiles, using them either as a design study, or as a commission for a customer. We'd like to know which one-off vehicle you like the most.
My pick would have to be the Jaguar XJ-13. Designed to race in Le Mans, it features a mid-mounted 500-horsepower 5.0-liter V12 connected to a five-speed manual, along some seriously stunning looks. Sadly, due to a lack of competitiveness and budget constraints, Jaguar never raced the XJ-13, and produced just a single prototype example. For a car so beautiful, it really is a shame.
Now we want to know: Which one-off car do you think is best? It doesn't have to be specifically old or new, or be a customer-ordered car. It can be any one-off vehicle out there, as long as you're a fan of it. Let us know in the comments below.
