Any ideas why my truck is not selling?

[desertPOS]

I have my truck for sale here:

But it's just not selling. I started out asking $4500 for it and now the price has fallen back down to $3200. I think I just may keep it, but I can't figure out why it didn't sell pretty quick at that price. Figured this is the best place to get opinions. I was thinking maybe since it has old tires could be part of it/ plus most people probably don't like the stock rims... Anyway, it'd be cool to hear anyone's thoughts. I thought gas prices may have something to do with it as well... If this is a lame post just let me know, but I'd hate to get rid of it for way less than I could have gotten because of something little that is deterring everyone. Thanks,
