Welcome,
These type of roofs and interior where specially made for tax purposes. They are not separately as a replaceable part available.
And if you might find a roof lik that, you still have to do the interior and get it inspected by the road authorities for getting the tax benefits.
You also have to get it registered as a (private)company car, as a private person you won't get the lower tax rate.
You still want a high roof like that, check the used car websites, these models tend to pop up every once in a while...
KJ, ZJ and KK models where fitted with these type of roofs and interior also.
