Most people have not been able to find a similar size drop in replacement, however if you comfortable with a battery slightly smaller there are many that will work. This battery does not have heavy demands, only for starting the car, and a smaller amp rating will likely work also.

i had to replace my starter battery last year, I went with the advance auto battery as well. Was less expensive than the dealer, they had it in stock (my dealer had to order one) and after getting it I found it was physically identical to the Mercedes service replacement starter battery that was in the car - down to all the little battery case labels, stampings, etc.
Worked out fantastic, picked up and installedthe replacement the same day and I even got a "speed perks" discount on it
one thing, I don't think 2003 came up as a match for a advance battery when I was trying to find it but I was able to find it searching for a different year (I think I used 2006)

Try Interstate battery
I found a DIRECT replacement battery @ an Interstate Battery shop. To my amazement when they brought the battery up, it had MB OEM sticker on it, it was the exact same one they removed from my 2007 SL550, it was at cost of $150 vs $250 at the dealer. IF you have a location close by doesn't hurt to drive by, also Advance Auto would be a great place also, I bought my accessory battery there , perfect fit for half the cost. Good luck !!!

Oreilly's just got in on the R230 Starter Battery game. Seems someone in corporate figured out there was a market for them since almost every store in the area shows them in stock. I just waited all weekend for the dealer to order one for no reason. And remember, when replacing the starter battery, you must first disconnect the rear consumer battery, then install the front starter battery, then reconnect the rear consumer battery.

The start battery in these cars typically will last a very long time, it's the trunk battery that gets the hard work life. Typically a starter battery will last 7-8-9-10 years. I'm sure they come with something like, a three year warranty. Even if it only lasts 6 years, I'd be happy. Super Start Extreme Group Size V4 Top Mount Battery Part # V4EXTJ - is no longer $160 that's for sure, I got one and it cost $230 but I was happy to get one. A local Oreilly store may not have it in stock, you can pay for it and they'll bring it in and have it ready to pick up in a few days. When I got mine, they had a promotion where you get a $20 gift cars for buying a battery, I used that to buy a wheel washing brush that connects to the garden hose. My wheels are now cleaner than ever
