2018 Mercedes Sprinter, for one. There's a cup holder insert that looks pretty much like an ashtray. 2005 Scion xB has a change holder that's shaped oddly like a thing one could flick ashes into. Came with the cigarette lighter, too.

2011 Nissan Leaf, however, assumes that if you're saving polar bears, you're not a smoker. There is a 12VDC outlet buried in there, but even if you bought a lighter to fit, I wouldn't try to get to it while driving. As far as I recall, there's no place to use as an ash tray.
