My uncle used to use wire coat hangers to hold things down in his car engine. But tennis balls - wouldn't you need to replace them frequently? They do lose their bounce after a spell.

I don't think much would even happen if the busted...The car might settle a little.

very good :)

Considering that it was an Opal Vectra, the change probably actually improved safety, performance and handling.

Years ago, I had a friend who worked for the NY Dept of Motor Vehicles. He was one of the driving testers. He mentioned it was not unusual to have people arriving for their driving test with a tennis ball under the gas pedal. ???

He had some close calls during the tests over the years and had to retire early for stress related problems. :)

How did they spot the car? How did they know something was wrong?
