Shanghai GM has announced the prices for its new model, the Buick Excelle, due to be launched in China this August, Access Asia reported. Assembly began last month. The Excelle, based on GM-Daewoo's redesigned Lacetti [Nubira for export] model launched last November, is lightly restyled for China and fits nicely into the GM Shanghai model line above the previous generation Opel Corsa-based Buick Sail and below the GM North America-designed GL8 minivan and Regal sedan.
