Ive done hundreds of these kits.
I am not an installer, but I have sold hundreds of them over my nearly 17 years in the car business.
Sometimes the clips are wrong, OE clips need to be transfered, they dont come sewn right in certain area's.
As I said, I'm not an installer. However, since we are a reputable dealer, we stand behind the work we have performed on a vehicle, even if it was a sublet. Over the years, I've not had
any customers complain about their leather conversions. We don't see any issues with clips, of course, but we would certainly see issues with sewing that comes undone, etc. Either way, these issues you mention have
never been a problem for us. Perhaps this is a testament to Auto Trim Design more than it is to the Katskin company.
I mean who wants a brand new car torn apart. Dealerships lie to the customer and say they have a car with leather then just send it to a shop to get K.S. put on . Plastics on new cars are getting harder to take apart because of new "one-way" clips and sometimes things break .
I don't know which dealer(s) you have worked with, so I cannot comment about that. As for us, the reason we have Auto Trim install leather seats is because, on occasion, a customer will want to buy car X which didn't have factory leather interior. In the majority of cases, this happens because the customer doesn't want to buy the model with factory leather--it may be substantially more expensive than the lesser model, or perhaps the leather model bundles in other unwanted options such as a moonroof. In other situations, a customer will want their leather seats to be a color or design that the factory simply does not offer--a contrasting color, a two-tone design, or maybe some custom embroidery such as the Toyota picture shown above.
Long story short, I've personally dealt with a large number of people who wanted their new car modified to their desire. In every case, the end result was a satisfied customer. Based on these collective experiences, I would--and do--recommend Katskin interiors installed by Auto Trim Design to everyone.
