If its gonna be a daily driver, the w124 might be better suited for the job(its quite a challenge to park the w126 in Greenhills during Christmas time). But if its a long distance cruiser or a Sunday car then the w126 is the way to go. Having 3 different Benz models presently (w123,w124,w126) I'd have to say that the riding comfort of the w126 is worlds apart from the w123 and w124.
One thing to look out for on M103 engines (260) is the fuel distributor, make sure that it is in good shape, replacement costs about 100k for a brand new fuel distributor. If you decide to go for a diesel w126, a 300SD would be a better choice than a 300SDL because the OM617 of the 300SD is a proven performer while the OM603 of the 300SDL has a tendency of warping the cylinder heads when overheated, although the OM603 is also a good engine as long as it is well taken care of.
In terms of fuel consumption, I can only speak for both my w124 and w126 which have the same engine. The difference in fuel consumption of both cars is negligible, but the w124 is more responsive because of its lighter body.
