SL/R230: 2004 sl500 parts
Due to the low production numbers of the R230, it's going to be hard to find one. Ebay is probably your best bet just because of the national reach of sellers. I'd look for a seller who offers pre-painted parts for other MBZ cars, then contact them and see if they can get what you need for your car. Note that these bumpers will be just the "skin". You will have to disassemble your bumper and remove the inner parts (frame, insulators, energy absorbers, grilles, fog lights, etc.) It's not too difficult, but some of the parts may be riveted in place and some of the plastic bits like to get brittle and break. As for the grille, those are readily available all over eBay. Some people like the single-fin grilles, so if that's your choice, this might be a good time to upgrade.
I would not put any sort of additive into the transmission. You need to fix the leak. Your car should have the 722.9 7-speed, so the leak won't be old "pilot bushing" problem the 5-speed had. The 722.9's rarely leak, but I guess you could have a bad gasket. I have heard of a few cases where the seal at the shift lever linkage leaks, and that's a pain to replace. What I'd do is have the fluid and filter changed, which will include a new gasket and have the leak investigated then.
For your other issues, you need to take care of your leaks. The proper fluid for the ABC suspension is Pentosin CHF 11s. Absolutely do NOT put anything else in it. My advice is to find the leak, fix it, and do a fluid flush with a new filter.
