ProQuest's EPC solution offers fast, error-free searches by part name or number in addition to vehicle-specific parts. Comprehensive parts information for Toyota and Lexus passenger vehicles from 1969 to current is contained on a single DVD, which is updated monthly and delivered to dealers on a subscription basis. It also contains optional VIN decoding and filtering that displays vehicle-specific parts information by entering the VIN's last eight- digits.
