Mitsubishi, anything French, Ford. In that order.
Mitsubishi hasn't made a good car in 30 years. And even when they did, their cars were average at best. They were NEVER the best. There's not ever a reason to buy a Mitsubishi instead of something else. And how many are left on the road? You see 90s Accords, Camries, Altimas. But Galants? Only a few VR-4s are left. They're bad at everything.
Meanwhile, the French make ugly cars with bizarre packaging using unreliable everything and with the tinest, least refined motors imaginable.
And Ford. Well, like I say, Ford gets the easy stuff wrong and the weird stuff right. Some Fords are worth owning, but most are the personification of compromise and lack of direction. Crappy ergonomics, bizarre mechanical issues (spark plugs that break off in the head, dry dual clutch transmissions for no damn good reason other than they felt like it, first and second gen tauruses with transmissions slightly more robust than gold leaf in an oven...
And of course their physically gigantic and overly-complex DOHC V8s that struggle to make as much power as competitors' OHV V8s of comparable size, with torque delivery that rivals my VG33 in peakiness.
Oh, right. And an entire stable of over-promised and under-designed turbo engines that consume themselves from the inside out while offering horrendous fuel economy and little to no power advantage over comparable "all-motor" alternatives but with none of the refinement benefits of the increased cylinder counts.
Oh, and they think offering a 2.7 V6 as standard in a half-ton but NOT offering that motor in the midsizer is quite sane. A 2.0 is clearly enough for a 6000lb GVWR pickup.
Okay wait, I take it back.
VW gets all 3 top spots to themselves. I completely forgot about them, which says all you need to know. They're not terrible in the "holy crap how are you still in business" kind of way like Mitsubishi, they're just...below average at absolutely everything possible. And they're expensive. And they're insanely unreliable. And they're ugly. And they are usually cheap-feeling despite demanding import prices. And they can't decide if they are a fun car company, an everyone car company, a turbo funmobile company or a "here's a huge I4 in a generic 3 door because screw effort that's why" company, or a diesel sedan company, or an electric car compa...oh right.
They're just...wrong at every step. The golf R is pointless and uncompetitive now. The Jetta hasn't been fun for nearly a millenium. The Passat has gone from wide Jetta to 8-cylinder luxury midsizer to hyper-budget I4-only midsizer in a mere 20 years. There's literally no reason to ever buy a VW when any other option is available. For less money, with better features, generally better-looking, and far more reliably.
Yep, Volkswagen wins. The company that cares more about getting one over on their sibling Porsche than actually building good cars.
