It cracks me up when dealers pull that "only avail until tonight". If and when they call you back, tell them the new deal is $11K off because obviously the $10K is off the table as it expired
Alas, I do have a friend who got crushed by coming back the next day. What he had not realized was that none of the bosses were in the night he made a deal on the car he wanted and they had appraised his trade-in much higher than they should have (he had not done any research). So when he returned a day later, the deal had gone up $10K. Of course had he done any research (like yourself) he would have snatched up that original deal.
