In-show robot mode

Robot mode - I'm sure small details such as the yellow highlights on the elbow, knee, and wrist joints could help here as well as the white bit on the bottom part of the hood. Painting the window could be nice too, as well as making the lowest shoulder spikes red and white. Maybe a more silvery-color on the upper arms as opposed to the same gray as the legs.
I used misterfanwank's picture because I think he did the best job of positioning the head/torso to be the most screen accurate. I tried to do the best I could of not getting his hands in with him :/

Car Mode -Rims. Desperately rims. I feel like the car isn't KO without the gold rims. Minor details such as the yellow vent bits on the doors and the middle of the grill would help also.
On the backside... everything besides the molding is desired. There's the white bits above the exhausts, the exhausts themselves, and the whole taillight bar thing.
I also think the figure could use some solid black paint/stickers over the windows. I just think it'd look nice.
Overall, I think a reprolabels set for this guy would be a GODSEND. Not sure if they do wheels, though, so they might need painting. I'm really looking forward to owning him, and I know he has potential to be great with the right amount of attention and affection (from repro haha)
