Whilst chassis 502 and 507 were minimalist stripped out barchettas, 505 has the addition substantial overriders in the grille, full height windscreen plus front and rear bumpers. The rolling chassis originally had the 2.6 litre engine, but by the time that the bodywork and trim was completed in Italy, it appears that all chassis had received the 2992cc Vantage tuned engine, capable of producing 140bhp.
