That is exactly how they want you to think. Sticker prices at used car lots are blown out of the water for a reason. I can almost guarantee you they only have like $12k into it, especially if they are letting you think you talked them down to $15.5K.
BTW, the glove box is cooled by the AC so it doesn't get cold enough to keep drinks cold. It might keep a frozen one or one that is really cold that way for like 20 minutes or so. I would bet a good guess that you would be lucky to get them to the mid 60's in temp.
If it is what you want, go for it, but I personally wouldn't. No CC is worth it to me unless it has the VR6 and is 4motion.
Get that "pay attention to me" s*** out of here. Contribute or GTFO.
