Yeah, that won't work for me. I'm not going to send someone a pile of money and trust the car will be perfect. I may need to fly a couple of states away to buy a car. I want to do an inspection and test drive, hand the guy some money and get a title or some assurance the title will come from his financial institution and drive away in my new (to me) car.
I need to wrap my head around how to charge the car on my trip home.
My apologies to the OP for stealing this thread - hopefully they got their situation figured out.
It boils down to how many flights does the buyer want to make. We did it in one, it was completely done when he arrived. We did extensive FaceTime to go over every square inch. That was the only way if buyer wanted to take one trip.
You have to make two flights if you want it properly registered (which implies properly insured as well) and inspected (in person) before payment. If a bank holds a title that could take a week or more between paying it off and getting title. My case had no loan and I had the title. You need title to register it.
I don’t trust anyone driving the car registered my name or covered under my policy.
I prefer not get a bank or cashiers then hand someone the title and drive away. How do you know the Check is good. Wire transfers are not instant and may not go through on weekends.
So to me, everything is the same with or without supercharging. They are not driving away unless registered and insured. And if registered and insured you have everything you need to transfer accounts (we did transfer of accounts in 1/2 a day

). But if you can’t transfer accounts in time. Add buyer as guest. Let them prepay some supercharging and cut them off if they exceed it. They will have to trust owner with master account until it’s transferred.
Between being remote distance and the account it gets complicated. If local you have lots of other options. Like delivery the car and take your plates.
