Have you ever had the transmission oil changed?

Check your ATF, also when was the last time the ATF and filter were changes?

Crawl under your car and check that the vac lines are connected and not leaking.

If its a modern car with electronic 5 speed box then it will probably be the MAF sensor saying time for bed.
EDIT: It's a 230. No five speed box for this engine.

Mines an E230 (97) with 5 speed autobox
Mark - 3 things spring to mind off the top of my head:
Although the ATF/Gear oil and filter have been changed recently, who by and what with - ie was it proper 'Genuine' MB fluid? If you have the 5-spd box then you will need to find someone with the proper tool (dip stick!) to check that the level is still correct.
The fact that it usually happens after the car has been standing (from cold) may be related to the fact that there is a 'warm up' map on the ECU to bring the catalytic converters up to operating temperature quickly (hence it will hold the gear shifts out longer). Not saying that what you are experiencing is normal, just that it may exacerbate what you are experiencing.
And has already been said, A faulty MAF sensor (Mass Air-Flow) is a common failure for modern MB vehicles. Certainly worth investigating if you are having problems.
Good luck and hoping all turns out ok

Had identical issue with my (then new) straight six W210 E320 with the 5-speed auto box which when starting from cold held on to first gear for what seemed an eternity and then gave a kidney-jarring thump in to second gear.
Was explained by dealer as being an attempt to lengthen the life of the catalyser by warming up the engine quicker and reducing the amount of unburned fuel going through the exhaust system.
I sold the car at nearly 100K miles with a perfectly good gearbox and within-limits emission reading, so maybe there was something in the explanation.
