Just busting your chops!
I could careless if a car is faster than mine, just glad I get to drive mine and love every minute of it. Did not buy a brembo package 3.73 6mt to race in straight lines though, be a waste of good Pirelli Pzero rubber. I am always up for a friendly run although not running 150mph on any roads around here. I think Virginia's finest would lock us up and throw away the key and use our cars as unmarked pursuit vehicles.
I do agree with your suggestion for OP to drive the different ratios. I did and it was the 3.73 only Mustang I was going to buy, guess thats why they have options, huh? If I stay NA, might go to 4.10 eventually. Regardless Im good for now, no regrets.
