Factual error: The limo shown is a 1990 (or later) Cadillac. It has large halogen headlamps and not the dual headlamps of a 70-71.
Factual error: Curiously enough, Michelle's mess in the bathroom with the self-tanning spray seems to be mostly made by footprints everywhere (but you don't tan your palms and soles, and the bottom of the foot is what she is using to lean on the wall anyway) while the spray she continues to apply does not color the tiles and towel in the slightest and nothing drips from the smooth surfaces.
Factual error: The Marines in Afghanistan in 2003 are seen wearing MTVs (Modular Tactical Vest), when in reality they should be wearing IBAs (Interceptor Body Armor). The MTV was adopted by the Marines in 2006 to replace the IBA. Lance Corporal Coughlin (Evan Jonigkeit) is seen wearing an IBA but none of the other Marines are.
