Co-worker traded in his 05 GT for a 14GT. At first, he said he'd never trade his 05 for a new one; he didn't like the interior or the exterior changes.
He spent a couple hours driving the 14 over the weekend and was instantly converted. He now likes the interior & exterior lines; not caring so much about the retro look.
What really sold him is the extra power! He really loved that old car but said he loves this one too.
