Practicing their final notes before they go on song for paying customers, three 991-series Porsche 911 GT3 prototypes were caught at a filling station in Catalunya, Spain almost completely uncovered. According to the photographer (working with an iPhone), two of them (foreground in the photo above) were wearing a host of extras from the options list, while the third appears to be a prototype set up halfway between a traditional 911 and a GT3: it has five-bolt GT3-style wheels and central exhaust, but standard 911 front and rear bumpers and rear wing.
