When Jane is pulling up to the Clampett's with Drysdale in the car with her she's wearing sunglasses she didn't have on earlier. Then as she gets out after stopping they're gone again.
As Jane is driving Drysdale back to the bank her car is pulling onto a street with painted lines on it but in the next shot there are no lines. Also of note as they drive along a police car can be seen with someone pulled over behind Drysdale's head.
