2006 Ford Mustang V6 Premium 2dr Coupe (4.0L 6cyl 5M)
I bought mine new in July of 06. v6 Legend Lime w/pony package. I went with the V6 due to price and insurance cost. After adding a S&B CAI, Predator tune, and GT muffler, I bumped up the hp to that of a small block v8, about 240hp. A 4:10 is going in shortly to makeup for the automatic. The v6 is a great platform to start off on if your on a tight budget. Responds well to S/C's which take the v6 to the 310hp range. I don't have that many miles on the car, but I haven't had any issues with it. I still get many compliments from people when I am out and about. I have no regrets with this car. It's a blast.
Retro looks, color, A V6 that responds well to aftermarket hp parts, a decent sound system, my-color dash, bullitt wheels and of course all the attention the car still gets.
None really to speak of, maybe bring back the hip on the quarter panels and have louvers standard or optional on the quarter windows.
