Nerd Herd car
From Chuck Wiki
A Nerd Herder is a modified Toyota Matrix[1] with many added features.
A standard Buy More Herder includes all-wheel drive, MP3 capability, and GPS navigation. It's painted in the red-and-white "Nerd Herd" color scheme, rather than Buy More green and yellow.
In Chuck vs. the Sandworm, it is revealed that Chuck's Herder has been altered with a self-destruct system, an auxiliary set of controls for the passenger, and an ejection seat for the driver. The car is also designed with a "Detention mode" which is activated via key remote, cuffing the driver in place and keeping them detained until further notice.[2]
Since Chuck and Casey manage to destroy the herders on a fairly regular basis, the CIA presumably has several of the cars already modified that they can replace under Big Mike's nose.
