Even though it's old, it still has low kilometers. Put it up for what you think it's worth and if you don't get what you're looking for just keep it. Not worth letting go for 6k for the low kilometers that it has.
Another thing I would also do if you're really serious about selling is try and get it back as close as you can to OEM. Putting back the stock exhaust and stock rims if you still have them. OEM is a big selling point on kijiji. Plus then you can sell the rims and exhaust separately and make more of a profit. When people see that a car has mods they instantly think that its been abused.
