Autos of Dallas in mid-July purchased the 55,000-square-foot former Ewing Buick GMC dealership at 4472 W. Plano Parkway, Plano. The dealership, which sells pre-owned luxury vehicles, will relocated from Addison to its new 8-acre facility by September. The expansion will allow Autos of Dallas to nearly double its current inventory to 1,000 vehicles and will make it the largest independent auto dealer in Dallas and one of the largest in the U.S., according to the company. 972-484-9200. www.autosofdallas.com
