If you want to make a semi-big deal of it, talk to the General Manager of the dealership. The salesman is in it to sell cars for himself (understandable)...the GM wants to sell cars for the dealership period.
Respectfully explain to the GM what happened, but let them know you'll take your business elsewhere if they don't want your money. If they see you're a serious buyer - and it looks like you are - then not only can you order one like Tired said but you may be able to get a better deal out of it.
