From a Fellow Owner...
My service tech was at the last HCD drive, Paul Schotter. He works at Mission Chrysler on I-35. They do have a Viper Certified Tech on-site and you can reach him at (210)967-2020, Either Paul or Ray can help you out. I have had them install some custom brakes and do scheduled maintenance, not really had any serious repairs done, but others with Gen II and Gen IV have been there and from what I hear Paul did everything in his power to make things right and make sure the customer was happy. They only have one Viper Tech but rarely have Vipers in for repair so turn around time has also been very good as well. Please let him know I recommended you. Thanks.
