Try this:

xaml:

<Grid>
    <ListView x:Name="carList" VerticalAlignment="Top" MouseEnter="carList_MouseEnter">
        <ListView.ItemContainerStyle>
            <Style TargetType="{x:Type ListBoxItem}">
                <EventSetter Event="MouseEnter" Handler="ListBoxItem_MouseEnter" />
            </Style>
        </ListView.ItemContainerStyle>
        <ListView.View>
            <GridView>
                <GridViewColumn Header="Car" DisplayMemberBinding="{Binding Name}" Width="Auto"/>
                <GridViewColumn DisplayMemberBinding="{Binding Make}" Header="Make" Width="Auto"/>
                <GridViewColumn DisplayMemberBinding="{Binding Year}" Header="Year" Width="Auto"/>
            </GridView>
        </ListView.View>
    </ListView>
    <TextBox x:Name="textbox" Height="23" Margin="5,0,0,5" TextWrapping="Wrap" VerticalAlignment="Bottom"/>
</Grid>

cs:

private void ListBoxItem_MouseEnter(object s, MouseEventArgs e)
{
    var item = e.OriginalSource as ListBoxItem;
    var car = item.Content as Car;
    textbox.Text = car.Name;
}
