Another European model that's not making its case stateside is the 1 Series, the pricey half-brother of the 3 Series. The bulging headlamps and squat greenhouse create an awkward form because it's based on a five-door hatchback.

While sporting the same six-cylinder engines and technology as the bigger 3 Series, the 1 Series is like an adolescent that hasn't grown into proper form, and it's pricey to boot and barely quicker.

When you're facing $36,000 for a 135i, the gorgeous 335i is only six grand further. In this case, the price of maturity is well worth it.
