If you have good compression and the car runs fine, my guess would be the valve guide seals. They have to be replaced about every 75k miles on the M103. Just had mine done on my '89 300CE and as with you, I was using a quart about every 700 miles or so. No problems with the operation of the car, just a pain to keep having to add oil.
Did they replace the valve guide seals? That's my guess. Pretty simple if you have the right tools. The bottom end of these M103 engines are pretty indestructible and should go twice what you have before having to do a ring job.
