Decide the amount you would like to put down as a deposit on your chosen smart and confirm the term of your agreement. Throughout the agreement you pay the regular instalments over the agreed term until the remainder of its value is repaid.
Alternatively you could opt for a Hire Purchase agreement with a final lump sum payment. This option features a large payment you defer until the end of the agreement. When all the payments, including the lump sum, have been made you will own the bus.
All you have to decide is whether you want lower monthly payments with a lump sum payment at the end or simple fixed payments over an agreed term.
