Foreign Cars, Bugattis and Race Cars featured on Sunday at the Greenwich Concours d’Elegance

For 21 years, the proceeds from the Greenwich Concours have gone to support Americares, a health-focused relief and development organization that responds to people affected by poverty or disaster with life-changing medicine, medical supplies and health programs.

The American Bugatti Club is scheduled to display more than 20 authentic high-performance, French-built vintage Bugattis, while a circle of Ferraris is also expected to grace the field. Models from a 1953 Ferrari 166 MM Barchetta Open Racer to a 2015 Ferrari LaFerrari will cover a large part of Ferrari’s iconic 70-year history of building dynamic street and race cars.

Italy will also be represented by a fleet of other exotic Italian models, including a 1954 Lancia Aurelia B20 GT Series IV, a 1953 Fiat 1100/103 Cabriolet, a 1954 Siata 200CS Coupe, a 1969 Lamborghini Islero, and many others.

The Lime Rock Historic Festival, which is held on Labor Day weekend at the picturesque race track in Northwest Connecticut, will be recognized with a collection of vintage and historic race cars, in particular a 1937 Alta Le Mans, a 1954 Lancia D50A(r) and a 1953 Effyh. No, it’s not a typo; it comes from the initials of the car’s creators. Lime Rock’s president Skip Barber will present the race car awards at the 2:30 p.m. ceremony.

Bonhams will hold its popular auction at its tent on the field, which requires separate admission. The auction begins at 12 noon. Three Bugattis are among the cars scheduled for auction Sunday afternoon.
