My favorite memory of 11 Harrowhouse:
The TC has firewall insulation glued in place in the engine compartment, but the glue is not very good so the insulation does not stick too well to the firewall. It also gets saturated with oil/water which makes it heavy, making it even more likely the insulation will become detached from the firewall.
The insulation extends down to the area near the bottom of both fuel tanks, or the bottom of the car. When I first bought my car the insulation at the bottom of the car had become completely detached from the firewall. The insulation is one big sheet covering the entire firewall, so the only thing keeping the bottom section from falling away was its connection to the rest of the insulation.
But the bottom insulation drooped down below the car body, only an inch or two above the ground. It was quite visible when looking at the side of the car, and would drag when you hit a big bump.
In the chase scene I could see this same insulation hanging down below the car, dragging the ground on occasion. It made me smile. Looks like the problem I had was universal.
