I did some housekeeping to the list, including shortening that "Unknown Class" category and getting rid of some old stuff, so here's what's changed in this fleet list update as of October 3, 2012:

• Ford Mustang convertible is once again exact model-reservable
• Nissan Quest: tagged "R"
• Lincoln Navigator 4WD is back! Now LWAR (Luxury SUV), model-reservable in Prestige Collection (cross-listed in both Luxury SUV and Prestige categories)
• Yukon Denali - no longer Luxury SUV class label (and that category seems to have gone missing...)
• Nissan Murano (YQ) moved to Midsize SUV category
• Buick Lucerne tagged "G" (last reported in February at YYZ), moved to Premium (PCAR) category
• Removed "F" label from Ford Taurus (G, PCAR)
• Kia Sportage removed from list (last seen in 2010)
• Ford Escape Hybrid removed from list (last seen in 2007)
• Toyota Highlander Hybrid removed from list (last seen in 2009)
