When trying to defeatMelissa to be the ultimate street racer, use the RX7 (all level 3 performance mods). She is tougher than Eddy. Try to use shortcuts as much as possible. Avoid the tram past the second corner of the track. If you are next to her, ram her into the wall. She takes much longer to recover from a crash than you. Note: Save your nitrous until the end.
