Early on

Mr. Giotto Bizzarrini best known for prototyping the 1st Ferrari GTO and after leaving Ferrari making his own brand of race cars and putting them on the street.

This is the 1st Factory production Spyder S.I. Built from the original 1966 Geneva Prototype show car designed By Bizzarrini, Style Italia (S.I.). Only 2- Production Spyders were built from 1967 thru 1969 before Bizzarrini had closed the doors. This Spyder (S.I.) weighs is at 2835lbs, Chevy 327/420 bhp 2-seater all aluminum roadster. This was one and only Spyder (S.I.) ever ordered and sold to a American customer Mr. Harold Sarko from Detroit, Michigan. This 1st production Spyder started its life in late 1967 from the Body builder Stile Italia (S.I.) in co-operation with Sibona e Basano, Under Mr. Bizzarrini supervision. This 1st production Bizzarrini 5300 Spyder S.I. Serial #BA4108 was originally Painted in the color (Blue Metalized) and the roof design was shown with the center T-Top bar removed as a Targa or a full convertible (See attached article written by Mr Gino Baglio in late 1967). The Rear Roll bar made in steel and was removable, This is confirmed by Mr. Diomante See attached Document Dated 08/30/2010. Mr. Giotto Bizzarrini turned this 1st production Spyder S.I. over to Mr. Diomante to test his abilities to finish this spyder for the American customer Mr. Harold Sarko. Mr Diomante started out as a Body supplier from Torino, then in 1967 moved to Livorno where he was responsible for body selection and saw over final assembly for Bizzarrini S.P.A of livorno Italy. At the request of Mr. Harold Sarko, the American customer asked this 1st Spyder S.I body to be painted in (Red) BA4108 is the only production Spyder to have the new design chassis called (BA4). This chassis allowed for a Larger Interior Cockpit with the seats a little longer a center console was added with a well needed glove Box. This chassis aloud for Bizzarrini fully Independent rear suspension w/inboard Magnesium disc brake calipers w/12 solid rotors, Jag 2.88 geared rear end and Adjustable Koni shocks. This was completed in with keeping the same 95.6 wheel base as the IA3 chassis that were fitted with the De Dion suspension. The chassis flex still was a concern and under pressure to finish the Spyder (BA4 *108) it was agreed to add a center bar which became a T-Top. It was at this point the Steel Roll bar was bolted on along with the center bar – giving the appearance as a T-Top to allow for 2-small roofs to be removed and stored in the trunk. This did solve the flex problem.
The car was Sold New in 1968 and delivered to the US Customer where the Spyder was titled and plated in Detriot, Michigan. This Spyder then past hands to the Sassak Family in 1969 where this Spyder still remains over 50 years later.
