Im new to this community and I am finding a lot of helpful info here. I own a 04 SL550, 05 E55 AMG, and just purchased an 07 S550 4Matic. I was thinking about selling my E55 AMG. Has 23K Miles on it. Im curious to what I should ask for it? I can always bluebook it but I know I am not going to get that price. I was hoping you guys can give me some feedback on what I will probably get for it and where I can probably sell it. Im located in So. Cal.
Any feedback would be greatly appreciated.

Thank You,
Francis
