Yep. I have a 510.511 Carrera, prompted by Chuck's various posts on them, and really love it - up until then, I guess I'd seen it as one of the less desirable Carreras but Chuck convinced me and it had a lot of wrist time for a while. Incredibly legible watch for something with so many different needles and dials.

And it might upset the traditionalists, but I agree with you on the Autavias too - barring the Siffert, those are my favourite Autavias. I like them all too, all three PVDs and even the gold-plated one, not sure I could pick a favourite amongst them.
