Hi MBGary,
When I bought mine, there were 3 560SEC Euro versions for sale; I talked to the guy that bought one for $12,400 CDN and the other one was last listed at ~$10k, and is now gone. All had less than 100,000 kms. I can only assume that with the large number of BMWs and Mercedes to choose from here, that perhaps the value is a bit lower.
Sorry, not interested in selling it. As for the 300 hp figure, that comes from the Euro specs from this sheet: http://www.geocities.com/MotorCity/Flats/2188/Specifications.htm however, I think it is generally acknowledged that the 560 Euro had 300 hp/330 lb-ft.
Thanks for the feedback on the web page.
