There is no need to respond if you can't hold a civilised discourse and choose to descend into directed insults instead. One can't install a Ford made shock absorber on a Honda Civic and vice versa. The time of interchangeable spare parts came to an end some time in 1980-90's where the car manufacturers started actively embracing the vertical integration. If somebody makes compatible, third party parts, it is mostly for a small selection of performance and sports cars and is not mainstream. I just replaced the chipped and cracked windshield last week, and I had to wait for 2 months for the replacement to arrive because only the original glass existed out there, with no cheap Chinese alternatives being available – they don't exist, either. And I had a continuous problem with spare parts for my previous 20 years old car that was more than 10 years out of production, and the car manufacturer stopping making them after 10 years. Lucky for me it was just zero problems, but lately wear and tear turned every other annual safety inspection into a 1-2 week long wait with the mechanic trying to hunt something down. The last time they just gave up and fudged it. My new car comes with a non-negotiable condition of first five years of regular service getting done at an authorised dealership as a condition of the car warranty. If I were to do it elsewhere, the warranty would lapse automatically. After the end of the warranty, I can take my car wherever I want. No, you can't install your own or 3rd party software in a modern car, either. This is well known and is indisputable. So all of that rings true.
