The 05 will appeal to enthusiasts of all ages. It will especially move those who have witnesssed Mustang's history through the decades. Ultimately, the car will appeal to people in their 20s and 30s as well. When I picked up my car in San Diego today, people were all over it. The dealer says that guys were taking pictures of it all day long. Ladies of all ages were attracted to this car, just wanting to sit in it.
As far as who buys what, I bet the average GT buyer will be a guy like me: 40 yr olds who have owed Mustangs in the past. I think the V6 will be a very popular car with younger buyers. For $21,000 or so, they will be able to buy a gorgeous car with incredible power. After all, the current V-6 is only 15 hp shy of a 1990 GT.
It's a golden era for the Mustang!
