A decade ago, BMW and Mercedes-Benz has gone to six-cylinder base engines for their roadsters; now with better engine technology—especially turbocharging—they're returning to fours.
Like the Z4 28i, the Mercedes-Benz SLK 250 offers strong fuel economy, although the SLK tends to feel a bit bulkier.
The Infiniti G37 is also at the portly end of the scale, although its strong V-6 is an asset.
The Audi TT is more of a sports car in its current generation and is a lean-feeling alternative that costs less.
The Porsche Boxster stands as the most serious sports car in the group, and it's probably the top choice for those who also plan to take their car out on the track once in a while; the only disadvantage of the Porsche is that you get a little more interior noise.
