J.R.'s investigator Bum tells him that Cliff Barnes' driver Frank (aka Raheed Durrani) was found by Cliff as a kid on the streets of Islamabad 30 years ago, and that Cliff virtually adopted him by bringing him to America, putting him through school and college, bought him expensive things, etc. However, in the original series, Cliff never went to Islamabad, nor did he become a guardian or benefactor to any child from there. In fact, exactly 30 years earlier was when Cliff had taken an overdose and almost killed himself.
The police cruiser seen during the climax is a 2012 Chevrolet Impala although the livery of the Dallas Police Department is the pre-2010 version (white on blue). Also, the Impala has 5-spoke alloy rims, not available on the 9C1 police package. The standard DPD cruiser used in service since 2010 is the Dodge Charger.
