The events of Lucifer's Cross are tentatively set to take place in the year 2016. When I was still writing short fiction about these characters, I hadn't decided on that, yet, and the time period was the late 2000s.
In those stories, Miguel drove a shitty, half-restored late eighties Monte Carlo, his excuse being that it'd be classic in a few years.
Mitchell sounds like a much nicer "person" than Miguel, though. Haha.
