Used only 5 cars total to obtain the Lamborghini Murcielago, which the five cars are the Nissan 240SX, Mitsubishi Eclipse GT, Pontiac Firebird, Nissan Skyline GTR, and the ever-so-popular Lamborghini Gallardo. If you play your cards in this game right, you'll win simply. I had this game on August 14th, and I beat it today, with only a few hours of playing.
