Car loan interest is not currently deductible....only mortgage interest. The bill reinstates auto loan interest deductibility (for everyone not just seniors).

Left leaning opinion:
It's only deductible if your total itemized deductions exceed your standard deduction. Otherwise, it's just another congressional shell game to fool the general public.
