Cars are often one of the most, if not the most, expensive purchases people will make in their lives. It's not unreasonable to me to have extra protections for those purchases.
Anybody who disagrees, try living in the Phoenix metro with a family without a car. Good luck buying groceries, getting to the doctor, etc...
Cars, like houses, are in a special class of purchases that we as a society have decided need extra consumer protections because of the high cost involved.
