Welcome and congrats on a beautiful car. Deep Sea Blue is an awesome color. I go back and forth on which color I like better, DSB or LMB. Both look great! There's a wealth of info here, so read on.
I also owned an '06 Mustang GT. Manual Transmission (only way to go with a Mustang imo) and a Saleen supercharger. 475hp. Lots of fun, but my 1er has been my favorite car. I really enjoy the DCT as well.
