I can recommend Dublin Dodge (925-829-0800), which is right at the 680/580 interchange...Not super close to you, but might be worth the effort...
If you call, be sure to tell them I sent you (Tom Rosenberg, 96 RT/10) ask
for Paul Gilbert in service, he deals with all the VIper service co-ordination.
ALso, John Cesack (I am sure I mis-spelled his last name...sorry John) is the one and only Viper tech, he is very good, detailed, really cares about his work...Keith the service manager is also a major gear head/racer, although a bow tie guy...They are committed to excellent Viper service, but they are not flashy about it...
Be patient about scheduling, as they try to limit how many Vipers they take per week, as you know, many viper warranty jobs are money losers for the techs, so they need to mix in some minivan brake jobs to keep them whole financially.
Let me know if you want to discuss further.
