TCC’s Bottom Line
The 2013 Audi A3 wears its age well, and remains a sporty, versatile choice for compact hatchback buyers who can afford a little luxury. The 2013 BMW 1-Series is part small luxury coupe, part sports car, and if you're okay with a tight interior and a sometimes-frustrating iDrive, you'll find happiness. The 2013 Porsche Boxster is one of the most fun, stylish, and luxurious roadsters available.
