Did two one-day rentals last week. No longer an Exec, but took a look at both sections.
On Monday morning, Exec stalls were mostly small SUVs (2x Escape; 2x Rogue; Tiguan), a Maxima, and a Challenger. Emerald stalls were 3x Impalas ('13 and "Limited"); '13 Malibu LTZ; and a relatively new '14 Sonata. I took the Sonata, which had around 100 miles on the odometer.
Saturday afternoon, Exec stalls were also mostly small SUVs, including a Cherokee. The Emerald stalls had 3x Altimas; a '14 Passat (that I could've sworn had aluminum wheels, not the base wheel covers); and a Sonata (one of those anomalies with the Hybrid's wheels). I missed the Passat by minutes, so I took a '14 Altima with just over 1K miles.
