Personally, I would like to see more affordable options on the scheme.
One idea could be offering approved second hand vehicles through the scheme. Many nearly new cars are still very reliable and it could make larger or electric vehicles much more accessible for families who cannot afford high advance payments.
Another option might be allowing longer lease periods than the standard three years. A four or five year lease could reduce the monthly cost or advance payment and make some vehicles more affordable.
It would also be helpful if there was an option to purchase the car at the end of the lease for a reasonable price. Some people grow attached to their car and know its history, and it could be a good way to help disabled households keep a reliable vehicle without starting again every three years.
I also think more affordable larger vehicles would help families with disabled children who need extra space, as 7 seater options can be quite limited and often come with very high advance payments.
Just a few ideas that might make the scheme more accessible for people.
