I like Achilles plan also. But you might want to modify it and use Gary Almond. Do a search here, he is well respected for his honesty, Viper knowledge and careful transport. Schedule with him, send him the check, he shows up at sellers, gives them the check, takes the title AND the car, loads up and two days late he's in your drive. This is exactly what I would do.
Lee,
Thanks for the support and trust! I have done this for a couple of new owners and would be more than happy to help out with this transaction.
I've had a couple of experiences where the car (in one case a Ferrari Stradale) was represented as perfect by the dealer and was even inspected by a Ferrari club member. When I went to pick up the car I found a few flaws that I reported to the new buyer. He declined to buy the car. The dealer did the right thing and reimbursed the prospective buyer for my services even though I went home with an empty trailer. I've actually sent business to this dealer for the way he handled the whole matter.
