Which British spy car helps Mater investigate the conspiracy in Pixar’s Cars 2?

Finn McMissile is the British spy car who helps Mater investigate the conspiracy in Pixar’s Cars 2.

Finn is an experienced field agent for British intelligence. He mistakes Mater for an American agent after seeing him involved in a covert exchange, and Mater’s accidental involvement eventually becomes essential to stopping the plot against the World Grand Prix.

Finn is designed as a fictional grand-tourer spy car with visual influences from classic British espionage vehicles. Michael Caine voices him, giving the character a polished contrast with Mater’s informal tow-truck personality. Finn works with Holley Shiftwell, another British agent who becomes Mater’s partner.

The names are easy to mix up: Holley Shiftwell is the intelligence agent who works alongside Finn, while Professor Zündapp is one of the villains. Sir Miles Axlerod is the former oil tycoon whose public role conceals the larger conspiracy.
