"Rosebud" is a 2011-2018 Mercedes CLS but is not an AMG. You can see that the front bumper and wheels are both non-AMG. It could be a CLS 300, 350, or 400, but it is most likely a 500. The 500 has a 4.7 V8 Bi-Turbo, but the CLS 63 AMG has a 5.5 V8 Bi-Turbo. Getting 500+ more horsepower has been done (the fastest W218 CLS is 1100+ crank / 900+ Dyno as 2022) but was done on a completely stock motor. The "boring out the engine to 7.2" is impossible on this engine.

CIA documents have spelling errors in their headers. One has "privledged" instead of "privileged" and it's the document Nina Dobrev's character reviews on her laptop during the flight to Greece. The other is a paper file that says "Informatiion" instead of "Information" in a scene later on.

When they were supposed to fly from Philadelphia U.S. to Greece the scene of the Philadelphian airport was taken in reality in Greece. As a result in the background there is an airplane for the Greek Airline Aegeans. Which does not make sense to be in Philadelphia.
