Dammit, this is stupid. You need, what, 3 or 4 "good trips" as it says in the manual. You only get that by DRIVING THE DAMN CAR - what IDIOTS you are dealing with - let it sit 8 hours?

Dealer stupidity and mis-information really pisses me off. If you want to buy the car and have paid a deposit - tell the fools to let you take the car home for three days and drive the damn thing, two things happen:

1) You get to know the car and see that it has no real issues.
2) The car gets driven and the issue is resolved.

From the manual, you need "good trips" and that means start it, drive it and warm it to (I think) a water temp of at least 140F. THEN, it must sit and cool to under (I think) 100F. Now, start and run it AGAIN and repeat the process a few times. Problem solved.
