I've seen a few in Hemming's last year.....................912's are cheaper.
There is a guy with a pretty nice one in town (edit: it's a coupe), he paid a couple thousand for it, been offered $4,500 from a walk-up.
Many of the good convertibles are asking around $7,000.......................not from me.
