File this one under "test drives gone wrong."

A prospective Lamborghini owner took a 2012 Aventador LP700-4 out for a test drive along Highway 73 in Southern California and had nothing to return to the Newport Beach dealership but charred remains.

The vehicle caught fire and was engulfed in flames. Onlookers shot video – you'll see one above – as the Lamborghini burned on the road's southbound shoulder near Aliso Viejo.

The driver was unhurt, and witnesses seemed amused by the $370,000 vehicle going up in flames in front of their eyes. No official cause of the blaze has been determined yet.
