Pricing: On lot Vs on other dealer's lot Vs ordering
 

I see that a lot of people are getting Z's at near invoice, but which cars does that apply to? Just the cars the dealer has on the lot? Can one exepcted invoice pricing if the dealer has to locate the car or have it ordered?

I hope this wasn't already asked. I did some searching but didn't find anything.

You can get invoice on almost any car, on the lot, order, other dealers lot, but for anything not at that dealership you will pay extra. The extra will be for transportation cost to move the car from location to another.
Also watch out for dealer fees, many are happy to give invoice but make it back in a 500 dollar fee.
