TCC’s Bottom Line

The 2015 Audi TT is quick, fun, and stylish -- but it skips full sports-car credentials in favor of a little more practicality.

The 2015 BMW Z4 is on the pricier side of the roadster segment, but it offers a nice blend of comfort, sport, and technology.

The 2014 Mercedes-Benz SLK is the most conservative choice amongst its competitors, but the mini-SL makes for a charming, compelling choice.

TCC Likes

Flexible, punchy engines
Balanced handling
Confident all-wheel-drive traction

Strong, efficient base turbo four (28i)
Tight, quiet retractable hardtop
Good ride-and-handling balance

Four, six or eight cylinders
Tight, refined interior with the top up
Unified styling inside and out

TCC Dislikes

Cabin design looking dated
Numb steering
Pricey once you start adding options

Steering lacks feedback
Not much space
Somewhat cluttered dash

Tight for tall drivers
Tall front end
Not quite as sharp as Boxster, Z4
