Continuity mistake: Upon leaving their wedding, the couple are in a Cadillac limo. When the car arrives at the reception, it's a Lincoln.
Suggested correction: We see the car three times (getting in at wedding, on road, arriving at reception), and it is a Cadillac DeVille limo, about 1990 model year, in all three shots. Note the emblems on the hubcaps, tail lights and bumper.
