I agree in part, but with the insulated door and walls, it's a package deal. If you go R35 on the walls with an R4 door, you've still got an R4 door. (Not even sure if they make something as low as R4.)

Now, if the exterior of the garage is brick, and will be heated by the sun during the day, I say get as high as possible, because the brick has a heat capacity which will work against you. A heat sink like that exterior to your insulation is really unfortunate thermodynamically, but fashion dictates such.
