I'll be 70 in 3 months, I'm waiting for my '11 GT vert. I'm trading my C6 Vette vert because it got too hard on my knees getting in and out. Traded my '03 GT vert for the Vette, and am anxious to be back in a Mustang again. Had hot cars all my life, my first car would probably have been a Mustang, but they were still 9 years away at that time.
Do what you feel like, age is irrelevent.
