Same! What’s especially misleading is that most of the car manufacturer websites have a “Build your own” tool where you can select the features and options that you want, only to discover that no cars exist in that configuration.
Just go to the dealer and spec the car like you want it, put a deposit down and wait a few months for it to arrive. If you want something bespoke you can't expect it to be in inventory.
I don‘t get the problem. In germany you go to a desler and tell them you want this specific configuration, you sign a contract and 3-4 months later your specific build is delivered to the dealery.
Most car dealers in the US, at least for “normal” (ie, non-premium) car brands are extremely reluctant to custom order cars and often outright refuse to do so. They also tend to put subtle pressure on customers to buy something of the lot right now instead. The car buying experience is very different over here compared to Germany.
I generally buy Nissan because the local dealer is good. Generally the base models have what people want, it's only fancy interior or exterior add-ons that make you wait. Base models have ac, sat nav, cameras etc already. Generally you don't have to wait too long because the car is already built or there is one to that spec being built soon. I think the most I had to wait was 2 months
