The Thrill Of Victory. The Agony of Defeat. Rarely does one person get to experience such highs and lows within mere hours of each other, but when it happens, the comedown is often all the more painful. Just ask Santaquin, Utah resident David Dopp. The Frito-Lay truck driver won a green Lamborghini Murciélago LP640 Roadster, grand prize in the "Joe Schmo To Lambo " contest operated by Maverik gas stations and teamgive.org last month.Dopp, father of six, was finally presented the car on Saturday afternoon, after which he set about driving it around the neighborhood, giving rides to friends. His elation wouldn't last. Less than six hours after taking delivery of the Lamborghini , Dopp lost control of the 640-horsepower Italian, hopped a curb and spun it into an embankment 75 feet from the road. A witness, Miles Davis (yes, really), said that skid marks were evident on the road and that the car ended up facing the wrong direction. Neither Dopp nor his friend in the passenger seat were injured.Police say the accident was likely "speed-related," although Dopp reportedly says he was only doing 40-50 mph when he lost control of the car on a section of road with a 35-mph speed limit. Dopp maintains he might have hit some black ice or gravel.While the extent of the damage to the Lamborghini is not immediately clear, local publication InSantaquin News notes that Dopp has full insurance .
