It's people like you that don't maintain their vehicles who say they are garbage. Well, maybe they are garbage themselves because they don't maintain their vehicles. No vehicle is made to run maintenance free. I know people like you who never change their fluids, then say their vehicles are garbage. I do have a vast knowledge of different vehicles because I have read about them since I was a kid. I have only driven GM vehicles because I haven't had any reason to switch to a different brand. You don't believe me, because you don't have a clue, and haven't seen it. It is you who say I enjoy putting up with garbage, after I have told you my vehicles have lasted longer than and driven farther than other people's Hondas and Toyotas. You are called the doubting Thomas because you haven't seen what my experience is. And you don't know how the auto industry works. The car manufacturers only assemble cars for the most part. Most parts that go into cars are not produced by the car manufacturers themselves. They purchase their parts from other companies called parts suppliers. GM produces their own motors and transmissions for the most part. Aside from that, just about all the parts are made from outside companies. FYI, a couple of years ago, Toyota and Chrysler had a massive recall because their air bags were garbage. Both of them purchased air bags from Takata. GM never had a problem with air bags, because they used a different supplier. So, I will use the same reasoning you are using. Toyota is garbage for installing shitty air bags. That's just a small example. Just before that, again there was another government mandated recall for every single Toyota because their brakes were shit. I am happy to say that my last 2 GM vehicles never had a single recall. But of course you are the doubting Thomas who won't believe it because you haven't seen it.
You go off naming Mercedes, BMWs, and Teslas as great cars. Anybody can make expensive cars that the average person can't afford. Sure they are good when they are new, but after a few years, they are endless money pits. Grossly expensive parts that you can only get through new car dealerships with high markups and expensive repairs that your average mechanic can't or won't fix. I had a friend who told me over 10 years ago that the transmission on his Mercedes cost him over 10 grand to replace. Imagine how much it would cost now. I have no need for those cars that designed and purposely made to get people to empty their bank accounts.
