Thank you for the replies so far. I spoke with Jim Hatch a couple days ago. I have him on the hunt for what I am after. The customer of mine who requested these cars is one who is very anal retentive about maintenance and therefore will only settle for a low mileage car (which has been well cared for). He is willing to pay top dollar for the right car and I know they are out there. I have some customers with '90-'91 560SELs which are black/black and are in pristine shape but they have over 80K on their cars and this fellow is determined to find what I am guessing must be the "BEST" 560SEL and 500SL in the country.
If one with 50K or 60K pops up, I would be interested, but the records must be top scratch.
