I've used ebay, cars.com, craigslist and just yesterday listing one on autotrader.com. eBay depends on what you're selling IMO, cars.com has been a waste of time for my truck, craigslist generated a bunch of inquiries from people wanting it for next to nothing, and people who don't keep their word, tell you they're coming to see it, then don't show up, what can you say - it's free, we'll see what autotrader generates when it comes out in a few days.
So you are selling a 94 E320, that say's E550 AMG, which was never made in the W124 era, maby that's why you can't sell the car... Take off those foolish emblems, and just put an E320 one , lower your price (coz of the high mialage), and you will sell it for sure.
