After Sandy and Diane purchase the $200 car, the scene showing their arrival to St. Louis as they cross a bridge is actually downtown Chattanooga. The tallest buildings and St. Louis Arch were digitally added.
When Sandy first arrives to Miami, Florida to catch Diana at the salon. The scene starts with an aerial zoom in of a coastline, then a short cut to Sandy waiting in the car outside of the salon. The scene tries to depict Winter Park as just a short drive from Miami when in truth Winter Park is a suburban city of Orlando, FL, about a 5 hour drive outside South Beach.
