Mr. Webber has a full grasp of powerful new sports cars â in January he was in Southern California for sales training and track time with the 2013 Porsche 911 â but for his 35-mile commute to Herb Chambers Porsche in Boston, from Scituate, Mass., he drives a 1990 Volvo 740 with over 300,000 miles. âI just canât see the point of spending a lot of money driving a newer, racier car every day in city traffic when my old Volvo just wants to keep on going,â Mr. Webber said.
