Can Mako sites provide a payment calculator for shoppers?

Yes. You set the default interest rate, term, and an expected down payment as either a flat dollar amount or as a percentage of your car’s advertised price. Shoppers, or your sales pros working with prospects, may override defaults with a term, interest, and down payment that applies to their unique credit situation or repayment preferences.

Everything that your shoppers store stay in a referenced cookie for one year, or until they clear cookies from their browser. This way, even when your shoppers leave the site and come back, they'll still see the payment options that apply to their exact situation.
