There may be a tax-savings angle to that. Some states, like Nevada and Massachusetts, charge vehicle property tax based on the year of the car and buying a car "one year ahead" can result in a reduced rate for that year compared to same-year tax rate. That might short-term make leasing cheaper. I only noticed it in passing when I leased a vehicle there.
