I am wanting to sell my 15" rMBP (Early 2013) I upgraded it to the max when I bought it. 2.8GHz Quad-Core i7, 16GB RAM, 768GB Flash Storage. I paid over $3,200 for it. I thought Apple products usually have a good resell value, but haven't had luck in the past. Anyone have luck selling a top-end BTO system? Thanks in advance!
