When Jeff is driving up to Happy Lee's place, he drives past 1 VW Beetle and then pulls up beside another one. In the next shot, his car is seen parked away from it and that 2nd VW Beetle is positioned a little further back.
As Jeff walks up to Happy Lee's house, the front door is blue, when Happy Lee answers the door, the outer part is white.
Toward the end, Jeff is pursued by a Ford Cortina, reg OYR 877F, which crashes with a loud sound effect into a stainless steel lamppost. When you see the aftermath of this crash the bonnet (hood) has 'popped' up and there is smoke/steam coming from the engine. However the front of the car appears to be in an immaculate condition and the same applies to the lamppost.
