As much as I might enjoy an upgrade to a newer special edition Mustang, I believe having a terrific 2009 GT Premium will have to satisfy me. As a guy in my 70's and on my 6th Mustang, I want to ask for suggestions. Based on my driving habits, I don't think I need suspension, etc. upgrades. I did a K&N CAI (without tune) and a new axle back muffler exchange (ProFlow). The other mods are things like a billet fuel door, billet door lock pins, etc. My car has 56,600 miles (I got it from a dealer with 12,000 miles in 2010). I put underdrive pulleys on a 1992 GT, but the CAI is the only under the hood change I've made on this one. I have not added the sequential tail lights, but I like them, and they seem like a safety feature. Seats are in good shape. Any suggestions for changes that might make driving and ownership more fun. Thanks for any thoughts.
