 I have been very pleased for the most part with my 06 Mustang GT.  I think the retro styling of the car is great.  It's like driving a 60s Mustang only better.   The steering response is great and it corners like a dream.  I am 6'2 and have never had a car that felt this comfortable. The Shaker 500 sounds awesome.  I have had aftermarket setups that didn't sound as good.  I only have a couple complaints. The rubber strips used to seal the inside of the windows scratch the hell out of my window tint when running them up and down.  There is a rattling noise under hard acceleration that almost sounds like detonation; but I am running 92 octane fuel and have ruled that out.   Very impressed
