A Mazda3 and a Prius are such expensive cars?
A Prius would cost me £21,995 - around 16 times as much. Though there are far more expensive cars out there, that they can't even get basic security right is fairly disgraceful....
And if you take depreciation into account, you can do a bloody lot of repairs on a used car before it's more expensive than a new one with free repairs.
Any car theft will hurt a lot for most people.
