Mine's the same and I paid $25,000. Tax tag and registration were extra. I see you as $400 better deal than me. I think the dealer is trying to screw you. And attorney could shoot a letter over for a small fee. $750 is a large 'error' for the dealer to make, but a judge might say that the sale price is still reasonable and expected, therefore agreed to in good faith. It's not like they undercharged you $5000. A judge would see that as an obvious blunder and I wouldn't expect to be handed the keys in that case. It's all legal-ese, and irritating. You've got to decide: What will spoil your ownership experience more, knowing that the dealer probably ripped you an extra one, or going through the hassle of holding them to the deal and possibly loosing the ride altogether. If they sell the car to someone else as a fast move, you may not have time to get it back in your possession as the new Bullitt you obviously wanted.
I was real pissed when I struck a deal on another Bullitt and busted my butt getting over to sign the paperwork, only to find that they had sold it to someone else. What I'm sure happened is that my offer was a low ball, so they took it. And at just the right time, someone else walked in and paid them more on the spot. I was fumin'.
Dealers are dealers, whether it's cars, guns, drugs, or whatever. I see them as all the same. Sad reality.
