Yeah, I thought about obscuring that & probably should have. On the other hand, if you can find the answer based on a detail like that, I think you deserve the point. I have to wonder how hard this one would have been to solve without that.
BTW, between you & 250gto, I'm getting some interesting insights into how some people might go about solving an auto puzzle. (And to think I almost always have to use the lame tactic of luckily happening to recognize a photo I've seen before!)
