I went to a shop locally that does exotics like Ferrari’s, Bentley’s and Lambo’s, so it wasn’t cheap by any measure (would rather not say how much it cost tbh because it was a good percentage of what I paid for the car in the first place).
They mentioned that it was actually one of the more difficult seats they’ve had to do (glad I didn’t have the multicolour seats). It took two hides of really good quality leather and I saved some money because they reused the leather from the seat backs (where the pocket is etc) as it was very clean. They also re-dyed my headrests to match. Finally, I’d bought new seat heating elements that they installed for me too.
