What a big relief! I went to Torque Automotive to get pre-purchase inspection (PPI) of a hybrid car, because a test for a hybrid system was available here. Service advisor Micheaux Norman greeted us and one technician came out to test both 12v battery and hybrid battery cells, all of which turned out to be good. Further, they did PPI, too. Now I can buy any hybrid car with confidence, because of Torque Automotive. Thank you so much for your help.
