When tinting using a film, you'll notice the white dotted line on the 3 door's rear passenger windows more than you would on the 5 door passenger windows, that's for sure.
However, as for the rear windscreen, you'll notice the white lines will look the same regardless of whether you have either the 5 door or 3 door variant.
The only other option to avoid the white lines is to purchase factory tinted glass, albeit the much more expensive route!
