You have lots of choices for inspecting a car in the San Jose area.
1. American Airlines flies direct from DFW to San Jose, so you could pop in town to see the car yourself. Even if you use someone to help you inspect the car, seeing it for yourself is very much worth the few hundred dollars.
2. The Northern California region of the VCA is located very near there, so many members are available to help you. (The NorCal VCA President, Maurice Liang, literally wrote the book on used Vipers.) If the seller is a VCA member, it's likely we already know the car.
3. Hartzeim Dodge, in San Jose, has 2 very experienced Viper Technicians who could evaluate the car.
4. Valaya Automotive, in San Jose, is very experienced with Vipers, and they could evaluate the car.
