6. Infiniti G20
This short-stacked little sedan was notorious for being a cheap part of the Infiniti lineup. The brand was working on competing with other luxury brands from Toyota and Honda, but the cars coming out at the time were forgetful. The G20 was a particularly sad example of what a compact luxury car should not be. It was nothing more than a slightly fancier Sentra.
But the shoddy build quality and lightweight design made the car an impossible mix of what could have beens. The car never had a chance of competing against much more refined offerings from the Germans. The only thing that the G20 did have going for it was bulletproof reliability.
