As it has for the past few months, the Ford C-Max tops the best-deal list for hybrid cars, although the lease deal isn't quite as good this month.
Ford will now lease a C-Max for $149 per month for 36 months and $2,549 is due at the time of signing.
Last month, Ford asked for a lower $1,999 up front, but the annual mileage remains the same at 10,500 per year.
