Why do you say that modern cars have a design life of seven years?

Ordinary cars are basically built to last around seven years and then be recycled. The complexity that has been legislated into modern cars is such that numerous expensive components can fail, and if they do fail after around seven years the cost of replacing them can be more than the car is then worth so the car may not be worth repairing.
