WPF trim property value before binding

Question

I have bound the datagrid Type column with the property called Vehile of the dataobject. The value of the property for example is InventoryService.Car, InventoryService.Boat etc. I need to display only Car  or Boat and trim the remaining part that is InventoryService. How do I achieve that. My current code is as follows

 <DataGrid.Columns>

                        <DataGridTextColumn Header="Type" Binding="{Binding Path=Vehicle}" />

                        <DataGridTextColumn Header="Make" Binding="{Binding Path=Vehicle.Make}" />

                        <DataGridTextColumn Header="Model" Binding="{Binding Path=Vehicle.Model}" />

                        <DataGridTextColumn Header="No of Wheels" Binding="{Binding Path=Vehicle.NumberOfWheels}"/>

                        <DataGridTemplateColumn Header="Road Vechile">

                            <DataGridTemplateColumn.CellTemplate>

                                <DataTemplate>

                                    <CheckBox  IsChecked="{Binding Path=Vehicle.Environment,Mode=OneWay }"/>

                                </DataTemplate>

                            </DataGridTemplateColumn.CellTemplate>

                        </DataGridTemplateColumn>

                    </DataGrid.Columns>
