Looks real clean now! Depending on the mileage, $12K might not be an unreasonable expectation. As for the time of year, IMO, when someone needs a car, they NEEDA CAR, whether December or May!
I sold my gen 5 Celi in late Sept and started getting bummed after almost 2 weeks and no serious hits. Then suddenly I had 2 offers on the same DAMN NIGHT, both at my asking price! Ended up selling it for $500 over my price that weekend! So hang in there and good luck!!
