The usa engines last forever under harsh circumstances and sometimes only need checkup every 120k miles!
But the rest about usa cars is low quality and low tech. Italian cars are even wors, also crap engines. You are trolling perhaps?
We are talking maybe different things.
I agree with you about durability of American engines. And if one wants clinical, all around quality car - they should go German or Skoda.
But! Italian cars don't have crappy engines. Just sophisticated pieces of art. That's why they require maintenance.
You can hear and feel the difference between American engine vs. Italian engine. I have driven both. The response to throttle, the sound... Italians have it.
Best car I have had was Alfa Romeo 156 GTA with 3.2 (Busso) V6. Amazing sound. Yes, it required constant maintenance and still had problems but was awesome to drive. I think as close to Ferrari as your average laborer can get (and I understand there is still way to go)
