Wiesmann is celebrating it's 20th anniversary this year and to commemorate two decades of oddly attractive, highly desirable retro-mobiles, the automaker will roll out several special edition models during 2009. The first 20th Anniversary Model from Weismann is the MF4-S GT, and the follow-up model will be a convertible version of the V8-powered coupe.

The Wiesmann MF4 Roadster loses its roof but will gain a soft-top, with power provided by the same BMW-sourced 367hp, 4.0-liter V8. A MF4-S Roadster is also in the works, packing a 4.8-liter V8 putting out 420 hp.

Wiesmann plans to increase output from 250 to 350 units this year, but for the time being, sales will remain exclusively in Europe.
