“A friend was driving my 1984 Pontiac Fiero when the engine suddenly caught fire. After an investigation by the local fire department, they determined an oil like substance was sprayed on the manifold. My friend was arrested for arson & I was arrested for criminal solicitation. After going through the court procedures and being convicted of a felony I received a recall letter from Pontiac recalling my car for possible engine fire. The car was already gone though & I never received any compensation and have had a felony record following me for all of these years! …”
