Okay an Air Elemental with the concealment power should solve this problem, unless an Earth elemental is more appropriate. I figure Air since anyone trying to see or hear us would perceive our presense through energy transmitted through the air.
Here goes.
Summoning + Magic (

= 1 success

Okay, no spirit appears, still resist drain and try again.

I'm going to have him conceal the SUV since I've only got one service from this guy. I can only have one unbound elemental and it takes hours to bind an elemental so I suggest Collateral moves in front of the SUV and we provide a rear screen. Maybe we can have us appear on his GPS tracking unit or something which should negate the concealment for just him.
RJ, I know there are pollution factors to consider so let me know if the outcome is the same and I'll throw up an IC post.
