I see. It’s been the case for as long as I can remember that most, if not all, manufacturers have done this. From economy car brands to exotic brands, it is the standard practice. While I do not like it, I understand it to be what it is, and therefore try to do my homework when buying a car that I haven’t ordered from new, so to build in whatever costs it takes to get it to a state that I’d enjoy. Unless it is a dealer-installed option (which the manufacturer will usually specify as an “accessory” vs. “option,” the cost to you during the ordering process vs. the cost to you to buy it afterwards is usually very different. Now, at least, you are aware, and it should now be no surprise.
