Not really. A guy I was talking to on FChat is bringing his Spyker but I haven't heard of anything crazy.
You can honestly spot anywhere. The entire immediate Greenwich area is walkable in like half an hour. Greenwich Ave is the popular street but during the show, Arch St is the place to stay because that's where the spectator cars mainly come through. It intersects with Steamboat Rd, which is the extension of Greenwich Ave. You will find most cars on these three roads, but don't hesitate to take a random sidestreet or walk into a random garage because you might find something.
