1 mile when I first Test Drove the vehicle, 4 miles when I picked up the vehicle 3 days later. Extra mileage I am sure was from going to get gas. I usually seek out very low miles on the vehicles sitting on the lot before purchasing them. I the vehicle has a few hundred miles on it, then it could have been a dealer trade, or one that was test driven quite a bit. You can tell a dealer trade from the Sticker, it would list another dealers name.
My 2010 had 2 miles on it (after PDI and trip to fill up gas). I'd "ordered" the car a year before and was very clear with the salesman that I didn't want anybody but the PDI tech driving the car (mine was the 2nd Gen III delivered by the dealer, so I didn't want any curious types taking it for any joy rides). I've ordered many cars and they typically have under 5 miles on them, except Porsches, which are taken on a test drive as part of the factory quality process (so they typically have 8 - 10 miles on them).
6 - After seeing the video of loading cars on ships I can understand how the cars have a few miles from transportation.
3 miles here as well. Looks like all the Nor Cal people have ~3 miles on it - probably because all of our cars were delivered to the same port.
When I signed the paperwork 7 miles, but then again I did a test drive. Not sure of the mileage of the test drive, but it seems on track with the 2 miles being talked about of a fresh Prius.
2 on the odometer at the point of doing the paperwork. 3 on the odometer when it was parked in my driveway upon delivery. .
1.8 on my car when it was first shown to me. The salesman always makes a point of having me drive the one I want with him to make sure I understand the car (after 50 years of driving!). So when it was delivered it had 33 miles on it.
