The Vega was indeed a giant goose egg for GM but I take exception to your description of the lowly Pinto.
Based upon the tests performed for the National Highway Traffic Safety Administration and by the tremendous publicity generated over the problem, Ford agreed to recall all 1971 through 1976 Ford Pintos and 1975-76 Mercury Bobcat sedan and hatchback models for modifications to the fuel tank. The modifications included a longer fuel filler neck and a better clamp to keep it securely in the fuel tank, a better gas cap in some models, and placement of a plastic shield between the front of the fuel tank and the differential to protect the tank from the nuts and bolts on the differential and another along the right corner of the tank to protect it from the right rear shock absorber. Recall notices were mailed in September, 1978 and parts were to be at all dealers by September 15, 1978.
I take exception because you bring up one defect, namely an inability of a 1970's compact car to sustain a (according to NHTSA rules) THIRTY MILE AN HOUR rear end collision. I would be interested to know how many other 1970's compacts would would survive such collisions without any risk of fire. Updated variants of the famous Pinto engine still live on today. This Ford inline 4 is also one of the most dependable engines made.
What's next? The Corvair? The VW Beetle suffered the exact same defect, and so did numerous swing-axle vehicles of that era. The Corvair's issue was resolved by the middle of Year Two.
The Gremlin? Tell me, in your opinion, what was wrong, defective or unsafe about the Gremlin, please.
Tell us all specifically how US brand vehicles are "mostly crap".
Most Gremlins racked up well over 200 thousand miles or more in service, and the AMC straight six lived on as the 4.0 six cylinder
in Jeep vehicles all the way up until 2006. And the venerable AMC 6 is considered one of the most durable engines ever made.
The Lada started out as a well made reasonably priced Fiat 124. As a Fiat 124, it's a pretty good car.
Once the Russians got hold of the design, they RUINED it in ways which are specifically pointed out, namely suspension degradation, degrades in braking and steering, and ultimately, replacement of the original Fiat engine with a lesser power plant.
Chaika sedans were not even available to ordinary Soviets, only high ranking government officials and dignitaries owned them.
And here's the amazing thing...EVEN these HAND MADE special order vehicles, like the Chaika, which was loosely based on finagled 1958 Packard blueprints in part, was a rolling disaster.

So, your claims about cost are also meaningless, because if a hand made Chaika were ever to be sold retail, it would have cost more than the equivalent of a brand new top of the line MBZ S-Class to the average Soviet.
But there's good news! The Soviet Volga sedan, pictured below, turned out to actually be a pretty decent car, not too far removed from an early 1960's "Chevy II" style Nova.
So, why am I picking on Russian cars? Because I've ridden in and driven them.
And I've owned several American made compacts of the same era.
