Mexican muscle

Invented after the 1988 Accord was released by the Mexican demand. Commonly features purple bubbly tint from Pep Boys ($29), an exhaust big enough to smuggle watermelons ($10), and cheap, plastic, fake chrome, hub caps ($25). Ultimately, this machine has devastated the suburban streets in the US of A. This car still lives today--twenty years old and the potential to impress any twelve year old middle school girl.

4 cylinders. 2.0 liters. One Mexican. Pure Mexican muscle.
