Tesla interiors and glazing place real demands on an installer. Depending on the model and year, there may be large roof glass, frameless door glass or deeply shaped rear panels, each of which needs care to fit cleanly. There is also a lot of electronics and trim to work around. None of that is a problem for an experienced installer, but it is a good reason to choose one who has worked on your model before and to book the car in properly rather than squeezing it into a gap.
Ask a local tinter whether they carry Kepler film or can get it. For more information, see quick quote.
