Hi I think London taxi design is boring, even LTI TX4 London Taxi has better design but i suggest you to change it to a new version. You should be careful about some points e.g. main lines and the type of front and back lights should be the same but it can change to a newer and modern version by changing type of design lines and details.For example new BMW and Mercedes vehicles have many common points with their older versions. Meanwhile you can send me a private post or e-mail for more details.
