It depends who you talk to, many insurance companies and banks will insure/fund a car under 100ks as new providing you're the first owner, over 100ks and they want to call it a demo even if it wasn't registered.
As far as how many ks upon delivery that will vary greatly depending on where the dealer has to take it to get things done, some get things done on site, some have to drive the car to other places. I've never had a car arrive with over 50ks on it and if it did I'd be asking for a discount.
