Driver 1 - Hidden Cars

Theses cars are made for Undercover Mode, appearing some missions only. Out of it, They are normally unplayable on PS1. But with use of GameShark codes, we can drive them on Take a Ride. Interesting enough, Three of these cars appears to be unused. One from San Francisco and two from Los Angeles. Beware that just like playing on Newcastle, on PC you unlock the cars after completing the Undercover Mode. As well three cars that are exclusive to PC.
