In the hotel, Jake says the briefcase contains approx $250,000. There are 10 stacks of bills with two bundles in each stack. A bundle of bills contains 50 bills. So that would be a total of 100 bills/stack or 1000 total. The largest bill in circulation is the $100, thus no more than $100,000 could be in the briefcase (most people don't realize just how difficult it would be for a single person to carry large sums of money like $1,000,000 or $10,000,000 and how many suit/briefcases it would take to have such in "small, unmarked bills" but yet movie characters seem to be able to do so easily in even small bags.)
When Jake leaves the Hotel Room, he leaves with the suitcase full of money. When Diane and Jake are kissing in the front of the hotel and when they get in the Mercedes they only get in the front doors of the car and when they are driving there is no suitcase on anyone's lap. Later when they get to the Mansion the suitcase reappears.
When Jake gets his cell phone for the first time and checks his call record, he says "El Pollo Loco." The closest El Pollo Loco to Seattle (where the movie takes place) is in Reno, Nevada; a little too far for a phone call for Mexican food.
When pulling up the security file on Cedric's character, the driver's license shows W98745621. Based on Washington State's driver's license scheming, the correct license code would have began with RODGEJ_30. (The underscore would have been replaced by the characters middle initial. Also, the file shows the record as being inactive, yet the date terminated is not available.
