When Jerome is driving Havana, they are in a long wheelbase 'L' version of Lincoln Town Car, when they've arrived at her house and are having sex in the back, they are in a standard wheelbase version (it has a shorter quarter glass section in the rear door window).
At the courtyard restaurant, the shadows formed by the retaining wall move around between shots. In Christina's shots it's clear the sun is over her left shoulder, with the wall in shadow and the shots completed, perhaps, in the morning. In Harriet's, the shadow of the railing is on the ground, it must be around noon. In Stafford's the wall is lit up, so maybe it's the afternoon. Everyone's going to know the truth now. The truth being that movie makers have very little control over the sun.
