We’re all aware of who Bill Gates is as he’s remained one of the richest people in the world for the better part of two decades. But just like any other successful businessmen, Gates started off with relatively humble beginnings studying at Harvard University in the early 1970’s, before founding the company which has made him so wealthy, Microsoft, in 1975. Just four years after founding the company, Bill gates purchased an awesome Porsche 911 Turbo and registered it in Seattle, Washington. That same Porsche was then sold in the ’90’s, but has recently resurfaced and will be put up for auction with Gates’ signed registration details. The auction will be in Vienna, Austria in the coming days and we expect this particular 911 Turbo to fetch a handy amount. The current owner selling the car is said to have repainted the 911 to the bright blue seen in the above picture. He then got Porsche Classic to kick-start additional life into the sports car by uprating its standard 3.3-liter flat-six engine which when stock, produced 300HP. That was a mighty impressive feat for a car in that era. The 911 Turbo is expected to sell for between $55,500 and $71,000 when it’s put under the hammer on the June 6,2012. Even though it’s unclear how the Porsche made its way to Austria from the U.S., it is clear that it has lived a very privileged life and hopefully it goes to a suitable home.
