BG, look if you really want to. You could trade your Lexus in, and buy a reliable Ford. Think about all the parts/service and american jobs you would be helping if you did that.

Lexus parts for the most part are all foreign, and that won’t change. (Well, unless you get cheap knock-off parts that aren’t OEM quality, and then you’re talking about parts from Mexico).

Choices you make affect the very people that you are trying to “help”, used or new. If you really want to help (which it sounds like you do), then you should put the effort in to help american workers.

When you’ve reached that point, then let’s talk about trade tariffs and protectionism, and everything else. Some of which I don’t necessarily disagree with you 100%. But you do no favors by not understanding how businesses work, and how everything it integrated. And you probably won’t until you experience first hand the impact it has on your own wallet.
