 I'd always driven the 88 GT I owned (bought new) 7-8 months a year, and loved that 'new car' feeling I got whenever I put it on the road every April.  Once I saw the retro exterior styling on the '05, and I heard about its great performance, I knew I was going to buy one.  I kept the 88 GT for 19 yrs - I really liked it, but I finally ordered an '07 on the Z-plan. The '07 GT is head, mane, and shoulders above the '88 in every way I can think.  My 3 boys are going to have to fight me for this car when I get too old to drive it - hopefully when it becomes a true Ford classic in about 20 yrs.
