I'm wondering what my options might be in trading or selling my 2008 GT while still owing $21k. My goal in this process is to be lucky enough to get behind the wheel of an '03-'04 Cobra. Would it be best to throw $2-4k into my current note and try to sell it out right around $19k and then try and find a Cobra in that range? I'm not sure I'd have luck with a trade, but would the dealership work with me on something like this?
