It was easier than expected, cost to transfer ownership $10, 3 bottles of water while waiting$3 (hate bottled water, but forgot my nalgene in the rental... hopefully whoever finds it uses it) and time cost of waiting a few hours...  All said and done, it was a 9 hour day, met the owner at a Toyota dealer for a pre purchase inspection, which turned up a leaky water pump and clear check on everything else. Being the car is a used Prius, I am personally not competent in inspecting all the complex systems, so would recommend to anyone pay the $50 charge to have the professional stamp of approval. We agreed on the sale price including replacing the water pump right away and then took the seller to dinner, he helped drop off our rental car at the airport and then I drove him home. It was a great expierience and a perfect vehicle. All documentation and service records since new and original owner. The couple are professional musicans from PR and Cuba and where moving to Akron OH to teach and take better job offers than they could find in PR.
