I was always into Fords and BMWs. I have had various Mustangs and BMWs.
I can say without a doubt - BMW is in trouble with this new Mustang. I test drove a GT today and was blown away. Who in their right mind would buy an M3/M4 for $60-$75k, when you can get as nice of an interior (with premium trim), and an amazing exterior 2015 stang for less than $40k?
Ford has really upped the quality on these new Mustangs. I would say very close to BMW feel.
