Are Mustangs good to buy?

What is your question?

I have a 2005 Altima and I reeeaaallly want a Mustang. I can't drive a stick so it would have to be an automatic. I'm looking at the 2001-2005 body styles. Are they good? My fiance has had mustangs all his life and I have seen how hard it is to fix a Cobra but he has a 2005 GT now. Every time I ask someone their opinion about them , they always tell me that it will be high insurance and repair records. I have been paying 279 for full coverage every three months and he pays 117 a month so its about the same. I have had no accidents and no tickets and im 23f.
