You know what really bugs me? Opel Speedster, 810 Kg, 200 HP turbocharged, accelerates 0-100 Km/h as fast as the M3 CSL.
The M3 CSL being the fastest BMW at the moment doesn't beat an Opel?!
I wish there would be some kind of an M version on the base of the Z4. Light, excellent handling, latest technology, it would be a perfect base for an M powered engine. And I'm sure it would easily beat the Opel for performance, for handling is no question anyways, even thought it's Lotus technology to a really big part

.
I mean, the new M1 will beat the Opel, I guess, but that's gonna be a while, and it's also gonna be another price class.
But a roadster monster machine from BMW would be appropriate. What do you think?
