The 2008 LA Auto Show starting tonight will see the debut of the new 2010 Ford Mustang we revealed first in full for you last night— nearly 44 years after the original 1964 model made its debut on the show circuit. The Mustang's not only the original pony car, it's the only one to continuously sell for all 44 of those years. With such an established history, and with the new Challenger and Camaro nipping at its tail, we were skeptical of a redesign we were told was more an "evolution" rather than "revolution." We'd also been told not to expect any seriously new powertrain options for the 2010 model year. Despite those nagging concerns, what we've found may surprise even us.
