I like the hardtop, having all the glass rolled down.. but then I'm a little biased LOL. The kids like it when they ride back there, that way they can wave at the fords when we roar past..You guys are correct that they offered the hardtop after mid year in 68, this was the same time they added the decor package option (chrome grille with the brushed aluminum tail panel). I was always told, all other things being equal, the coups would quarter mile a little quicker because they were stiffer... But maybe that's just an old uncle's tale..
