If buyer and car dealer have executed a purchase agreement but waiting for delivery of car is the contract binding

Your facts are a little confusing. You say you executed a purchase contract, but then say in order to get the vehicle you have to execute a sales contract. Either way - need more information here. It sounds like the contract is hinged on 2008 pricing so the dealer may have to lock it in prior to end of year?

You're certainly not obligated to do anything, unless you want the car and the only way to get is to sign now. You should talk to the sales manager or general manager of the dealership to clarify the need for pre-payment and signing. Locking in the price could be done with a signed napkin theoretically, if the person signing had authority to do so.

Best of luck.
