I must have never voted on this or posted in it the whole time I've been here!
I got my 2005 when I was 30 and I just turned 35 last month. It's my second actual Mustang.
I got a '90 2.3L LX when I was 17, drove it for 6 years. Overlapping that was an '87 Turbo Coupe that I had for 7 years. This car is my first official gas V8 vehicle, I also had a '94 F250 diesel for a few years (miss that truck) and my current 2009 Ranger (hauler/winter vehicle). As you can tell I'm a Ford guy, and everything has had a manual transmission except the Ranger (I won the Ranger in an auction so I couldn't really be picky on the transmission type)
