First off, this is not an actual SL65 AMG Black Series. What Inden Design has done is make a car for those who like the Black Series, but would like it with the retractable hardtop that can be found on the regular SL65 AMG. The bodykit does a good job of copying the Black Series vented hood, flared wheel arches and side skirts. The ECU is reprogrammed to produce 680 horsepower, which is actually more than the Black Series' 661. All in all, it is a well-done facsimile.
