You might also check out Daniel Schmitt & Co. in St. Louis. They specialize in cars like that. However, if it was me, I wouldn't limit myself so much on mileage. Finding a black on black 90/91 560 with all records might be challanging, but possible. To find one like that AND under 40k...I'd say would be like the proverbial needle in a haystack. Mileage isn't as important if the car was meticulously maintained. I think that is the key here, maintenence, not mileage...granted it's some off the wall number. I would much rather have spotless, meticulously maintained car with an anal-retentive PO with 80k on it than one with 40k that wasn't cared for. If it were me I would raise the mileage limit to maybe 75k or so....still with all records naturally. Just my $0.02.
