Do you offer a 5 month lease for May through September.
Cargurus doesn't sell, finance or lease vehicles. You will need to contact a dealer for a lease. This is a ad site like other car online sites.
Leases are long term; usually a year or more. Rentals are short term, and that's what you should pursue. As an alternative, you might consider buying a car and selling it four months later. That resulting cost would be less than a rental, and there are places where you can sell a used car quickly.
