The Jag's interior is poorly detailed on so many levels... On pictures and even in real life, I felt completely underwhelmed by the materials used, the ergonomics and the feel of the whole thing. The SL, on the other hand, has an interior that actually relaxes the driver. Its laid-back, wide and feels like a space-ship. Pity for those plastic buttons though, thought MB would have done at least a materials reworking for that. Otherwise, the SL's interior is as good as roadster interiors can go.
