I was Preapproved from my credit union for:
I am assuming the buyers order is a proof of purchase.
As for the insurance it is easy. Once you find the car you want you can take or call an agent with the vin and get make the purchase of insurance, send the proof to the lender and go pick up the car. You can purchase the insurance prior to the vehicle because it does you no good to try and file a claim until you actually own it so fraud is not an issue.
Best of luck.
Assuming your correct, I can't have proof of purchase without the loan to buy the car.
As far as the insurance, this is only a preapproved loan, (spell checked changed the preapproved). I fixed it. So I dont want to buy insurance on a car I'm not sure I can get.
