I think you cant go wrong with the Twist-Nova combo like you have in your cart right now. For even more discretion, a Mini Vivi Nova or a Kanger T3 may be worth looking into - they blend in much better with an eGo. The big Nova has slightly smaller diameter than the cone skirt you have in your cart and could look silly and irritating if you like things neat like i do.
Also, if you spend a lot of time in your car, get a passthrough and a car charger, and never run out of battery again!
If you dont want to raise the question of doing "other substances", a cigalike maybe what youre looking for. Most people while not familiar with all the PV systems we use do know by this point that there exist electronic cigarettes, so seeing something that looks like a cig will put their minds at ease.
