Frequently asked questions
Should I shop by monthly payment?
No. Negotiate price and financing separately, then compare amount financed, APR, term, fees, and total cost.
Does lease versus buy include every charge?
Only the values entered. Obtain the lease disclosure and purchase quotes because mileage, disposition, wear, tax, and acquisition rules vary.
