I have a 1976 Chevy Dually 1 ton truck.
I bought it in April, 1986 with 100,000 miles on it. It now has 350,000 on it.
I have about 15 keys hanging on that key chain. NEVER had a single problem.
They are trying their best to remove weight from every new car in every possible place to get batter mileage.
Don’t want a plastic car myself.
