Often refferred to as Prizmas Maxiums, or Priz-omb, or the Priz-omb I presume.
Long def: A great little econobox that was underrated because of its association with lame Geos like the Metro (no relation). Like the Chevy Nova it replaced, the Prizm was a 99% copy of the Corolla, built by the same people at the same plant. Went through three generations (89-92 and 93-97 as a Geo, 98-02 as a Chevy) before being replaced by the Pontiac Vibe.
Drives nice, rides nice, has good power (with 1.8L engine), scores 30 MPG, and might outlive you.
