RaceTrac Petroleum Inc. just inked a long-term lease at Cobb County’s 200 Galleria tower, turning down overtures from multiple developers that wanted to build the company a new headquarters. RaceTrac will initially lease the 6th, 7th, 8th, 10th and 12th floors, but could expand to occupy up to 144,000 square feet within the 20-story building. RaceTrac was courted by developers, but the company could not justify spending up to $38 a foot to rent a newly built tower when existing space was more affordable.
