if you have the means then you could probably buy something second hand for less than a years pip etc.
the advantage of the scheme is it includes everything except fuel.
if your low mileage and short journies and can get by with a manual then in purely monetary terms you would be better off going the private route.
in pureley monetary terms i know i could save money by getting a second hand car, but i like the security and conveniance of the scheme.
your choice.
