Retro is like everything. It can be done well or badly. It’s not as bad as it was around the turn of the millennium when retro was EVERYWHERE but retro for retros sake is generally a bad idea. However if a manufacturer has an iconic vehicle they are potentially sitting on a feel good goldmine and they’d be remiss not to leverage some of that heritage.
Land Rover could have gone the retro route with the new Defender but did something astonishingly modern that looks like nothing else on the road. The Challenger still looks great and it’s been on sale for what, 10 years now? The less said about the Camaro the better.
