Contract Purchase works in a very similar way to Contract Hire. You pay fixed monthly Payments for a new vehicle of your choice over 12 to 60 months, there is an initial payment and then at the end of contract you have the option to buy the vehicle for the remaining value, or Guaranteed Minimum Future Value (GMFV). The GMFV is calculated at the start of the contract so you can accurately forecast the cost of purchase. If you decide not to buy the vehicle at the end of contract you simply hand it back with no extra charge.
