My son has been waiting for a big ol' Ford truck for work. His employer provides the truck for him which is good because he drives 100 miles a day round trip for work and it's also for his personal use. It has 159,000 miles on it and he is in desperate need for the new one but it is delayed because of the micro processor deal mentioned.
I guess there's lots of vehicles built but sitting there waiting for the "brain" to be installed.
