The average consumer purchases an automobile every four years. Auto sales have been slow for several years so the first sign of an economic recovery will bolster consumer confidence. If the economy shows signs of recovery which it should by the 1st or 2nd quarter of 2010 I believe you will see auto sales soar and since Ford owns their own finance company and has successfully renogiated their contract with the UAW they will be in the best position of any domestic manufacturer.
I believe you will see Ford trading upwards of $15-$20 per share in the next 18 months.
