1953 Jaguar C-Type. The C-Type is a legend. It won its very first race and won Le Mans twice in three years. Recent auction results: Bonhams, November 2013 — $4,751,464. There were TWO authentic C-Types at this event.
The white car is a '65 289 Shelby Cobra. Not a kit car or reproduction, the real deal.
Your post is a gentle reminder that many of these aren't easily recognizable. If I get some time this afternoon or evening I'll go back and annotate properly.
In the meantime, are there any others that require a quick ID?
Exactly. Contrary to popular belief, the natural habitat of these cars isn't on display at the golf course or hidden in a garage.
These guys in particular were hooning the snot out of this old Maserati Ghibli Spyder. They're milliseconds from a hard right hand turn. Technically it's not a great photo, but you can totally get the sense of speed (and see the body roll).
