That should be trivial with decent insulation and not a lot of
additional heat.
I took a quick look, so someone needs to check my math.
Using round numbers at 8 cubic feet.
A box 2x2x2' has 24 square feet of surface.
If it's 50F in the car, that's 100F difference.
Two inches of foam insulation should be about R10.
Loss 240 BTU/Hr >> 70 watts...unless I screwed up the math.

Hardly seems worth messing with the cooling system or exhaust.
