I clearly remember one warm 28 degree day in LA when I was driving my Mustang Fastback that didn't have power windows, power steering, power brakes, GPRS satellite navigation, air conditioning, cup holders, xenon lights, or bluetooth in-car telephone systems, etc… Yes, the brakes and steering were hard to operate and my face and back were wet with sweat but the sensation and indescribable high I got from driving the car down the highway was something you'd never experience from driving a modern sedan or sports car.

我清楚记得一个在洛城的日子，户外温度大约摄氏28度，我开著一辆揭背式野马。那辆车没有电动窗，没有动力方向盘，没有动力辅助煞车，没有GPRS卫星导航系统，没有冷气空调，没有杯座，没有氙气车灯，没有内装蓝牙电话系统…等等。煞车跟方向盘都很难控制，我的脸和背布满了汗珠，但是当我开上快速道路时，我内心兴高采烈的程度是你在现代的轿车或跑车身上完全无法体验得到的。
