Upon return at LGA today I saw a Cadillac XT5, Chevy Malibu, Chevy Impala and some other non-exciting vehicles. The yellow RS Convertible was in the upgrade slot.
At my pickup time earlier this week there were Camrys, a Q60, a few 300s, and some other non exciting vehicles. In the upgrade slots were 2 Q50s, a QX70 and something else that I don't remember.
