Chrysler Crossfire SRT-6 convertible - unless someone purchased the
rear wing afterwards, this is my first SRT-6 sighting.
Wheels match too, and that's an SRT-6 color. Very rare car - possibly rarer than the Viper.
Audi S6 2007 - can't believe I got this. I had only a few seconds between realization and that shot. You can see the LEDs in the front bumper, and just make out the V10 badge (top left of image).
Fantastic sighting. Did you take this this week? I had no idea they were out yet.
