I do agree 100% about getting insurance on it BEFORE you let the tires touch pavement.....too many things can go wrong and put you in a world of hurt.......My agent "knows" that I am always getting vehicles....some never hit the road again, after I drive them home, and others are just beaters to get me by while working on my baby.....He has always told me to call with the vin and the details(make, model, year) and if he isn't there to make sure to leave a detailed message including those things. At least this way I have proof that I asked for insurance time and dated before I drove away, and he has told me many times he will stand in court to defend me if need be.
Now everyone might not have a good "relationship" with an actual person for an insurance agent.....I won't do important business with a phone to who knows where.
Again, the op needs to remember one thing........PYA.....Protect Your A--!! Find out from the source don't just risk it, and at lease ask your agent if you can call in your vin when you get there to at least get it insured to get it home.....even if it is just a one day add to your policy.
