15. Alfa Romeo 164
Alfa Romeo left America in 1995 only to return in 2009. However, the last model Alfa sold in America was a gorgeous 164 Sedan with a famous Busso 3.0-litre V6 engine with 210 HP. With 0 to 60 mph time of around 7.5 seconds, a precise manual gearbox, and excellent handling, the 164 was a cool sedan that should have appealed to US buyers.
Due to poor management, marketing, and dealer support, performance-oriented American buyers simply didn’t know how good the Alfa 164 was. Ultimately, the model flopped in the States (via AutoTrader).
