It's at the StatesVille auction in North Carolina. You have to have full dealer credentials to get in. Manheim is a network of car auctions throughout the US, there's one in pretty much every major city. It's scheduled for sale tomorrow, the 13th. I always am on the look out for Insight's that go through them, at least here. But when there is something wrong with the car, like if it's been hit there will be a note so I look at the listings a few times a week and as bad as it sounds I've been keeping a list of vin numbers to avoid.
Still, you can find some good ones from time to time. A lot of times when cars are trade in's at dealerships they go through these auctions. Thats where mine came from.
