When leasing, you are not buying or financing a car in the traditional sense and therefore you cannot part-exchange your current car against a leasing deal.
However, some dealers may buy your current car from you and you can use these funds for the initial payment on your leasing agreement.
To find out more, simply contact your chosen dealership and they will happily advise on your options.
