I'm not sure how much of an investment a Mustang would be. The only reason I say that is the simple fact that the market is absolutely FLOODED with them. For example, there is a guy here in town that sells them, he probably has 15 of them on his lot at any given time and he has been there the entire 5 years we have lived here. He buys them, sells them, puts tons mods on them etc. the kids around here love them etc. The cars he sells sell from $3900 up.

So all in all IMO unless you have something really really rare, I'm not too sure they would be a good investment. A good friend of mine just sold his 09 GT500KR, he paid 83k new and sold it for 65k. Granted, he prob should have kept it in a garage for another 30 years and then maybe he might have made money, but then again, maybe not. I got to drive that car just before he sold not too long ago, and I must admit, that was one Mustang that was actually worth driving!
