I don't think so, at least not available in the US (the 4 banger version is not available in the US either I don't think). List is 45k but of course that is completely devoid of any options. Most people are paying 50-55k

The 170 forum has an immense amount of info of interest to xfire owners.

114,000 posts or so.
In fact, I found out about the xfire on that forum when I was looking for a used slk320 manual (a hopeless quest), so I'm very happy with the xfire, though I think its price will have to go down even further after the 171 hits the lots.
