hi, i know how much of pain that is....you can try these guys : http://www.trim-tech.co.uk/
....they did my car and its quite invisble to begin with but over time you can see a ring where they repaired it (no hole though) -although it might be less obvious with a cream interior.
the problem is that these invisble repairs are usually for used cars being 'touched up' for sale, so its not very permanent for areas that are constantly in use. i also had it done for the fabric on the A-pillar and its looked as new since.
