New vehicle buyers determine quality by the whole ownership experience, not just parts, San-Diego based research firm Strategic Vision said as it released the results of its 2003 Total Quality Index (TQI), that measures the complete ownership experience, including the emotions generated -- the same criteria it said that buyers use to measure quality. Problems reported in other indices didn't keep owners of vehicles such as the Mini Cooper (912 out of 1000 possible) and the Hummer H2 (902) from rating them highly.
