How much does an average car weigh?
Average U.S. Car Is Tipping Scales at 4,000 Pounds
The E.P.A.'s weight statistics show that the average weight of a 2003 car or light-duty truck, like a pickup, sport utility, van or minivan, was heavier than in any model year since 1976, when the average peaked at 4,079 pounds. Just five years later, after the oil shocks of the 1970's, the average had fallen by more than 20 percent, to 3,202 pounds. The figures take into account the sales volumes of different models.
Average fuel economy peaked at 22.1 miles to the gallon in the late 1980's, according to the agency, but has eroded since then to 20.7 miles for the 2003 model year.
The agency expects the 2004 model year to finish with an average weight of 4,066 pounds.

My 2001 Nissan Altima weighs 2945 pounds. I believe it is an average sized car. My Ford Cargo Van weighs 5271 pounds, for comparison.
The Beetle wiring loom wouldn't weigh that much compared to other car wiring looms due to the lack of air conditioning ( at least for the majority of them) and heater systems wiring. Modern vehicles have much heavier looms due to the complexity of electronics involved. I have not found a source that gave weights for wiring looms.
