I'm playing Death Rally on the iPhone and I'm stuck at 124% out of 126% I've got max cars and weapon upgrades. I've beat the adversary.
My fame level is at God level. Looking through the options "stats" I don't see any stat with x/y not fulfilled. I haven't killed every boss type according to the stats or won races on every difficulty.
Anything anyone can think of that makes up that last 2% to complete a career.
