While we agree that this economic environment is less than optimal in terms of consumers' financial capacity, sales continue because the there is an absolute need to replace those cars that wear out. Every year the industry loses 14 million vehicles to the scrap yard, so every year in which new car production is less than scrap removal, the total population of cars on the road declines.
In addition, the number of potential drivers increases every year due to the natural growth rate of the population. (Note: this fact has been obscured lately due to the underemployment rate of close to 17% which will reverse with a vengeance when the economy finally improves)
