The Ranchero was first, then copied by Chev.So why did Ford discontinue the Sport Trac now only years later to bring back the Maverick with very similar size and styling? Or the original boxy Escape now to have a very similar Bronco Sport? Or for that matter, the original Bronco, now finally back and closer to the original? Styles come and go. Back when Chevy had the El Camino, Ford tried a similar concept with the Ranchero. I don't think it did as well.
My point is that styles change and variety is good. So you prefer the Maverick looks. Fine. Just so there's alternatives for those who want something a little different.
