Do I have a chance of winning this DUI case since I never turned the car on?

On July 05, 2014, I let myself become extremely intoxicated at a bar, and stumbled out of the bar, where police were called. As they were pulling in, I was walking to my vehicle that was in a parking spot at a local grocery store with other shops, and made it to the driver's seat. I never turned the car on, and the officer states she saw hand movement pulling keys out. I blew a 0.24 at the station, which is very high. The deal is first offense DUI, with BAC certificate removed from table. Therefore no mandatory jail. Although I was wrong for being very intoxicated, the vehicle was not operated at any point, I was not on a highway by definition, and I was cooperative. Should I gamble and take this to bench trial? Lesson learned either way for sure as this is the most negative experience I've ever had. Regards.
