18、ce . Compared with stre ngth type machi ning cen ter it, the structure is complicated, the floor space is large, quality is large, the price is high.Sitti ng alon gside the all-new Focus, the Focus Vign ale Con cept on display at the Shan ghai Intern atio nal Motor Show is a on e-off desig n study t

19、hat explores the pote ntial for future Focus derivatives.The Focus Vig nale Con cept takes its in spirati on and name from the renowned Italian designer, Alfredo Vignale （19131969）, who has an historical connection with Ford s European design heritage.His CarrozzeriaVign ale compa ny produced many s
