I am thinking of ordering a Model S (85kWh), after I can get myself to Florida for a test drive, and getting it mostly financed. As I understand it, I should apply for financing close to delivery due to the 30-day period loan applications usually stay open. However, I am uncomfortable not knowing before ordering how much and at what rate loan I can get. I just don't want to be surprised. If I apply for a loan pre-approval now, it will expire before payment time. But would there be any negative consequences of that on my credit score or re-application?
