I've been working on a 'magnum opus' - an alternate history of GM that is 'counterfactual' but based on real premises - sometimes even misprints or mis-reporting by contemporary magazines of the time.
When you're writing a 'false' history you often come to see that not everything can be improved upon - especially in the 'supercar' aka muscle era. But every rule has an exception.
One of the exceptions is for the '78 A body redesign. This is a case where a simple alteration can radically improve the car. In this case simply retaining the wheelbase of the two door A body ("G body" in the alternate universe it ) of 112" for all of the new intermediates instead of the 108" wheelbase. It's just a case where they went a bridge too far in downsizing.
Even if the cars were exactly the same length they just look infinitely better - even more 'normal' with four additional inches from firewall to the front hubs. It would have had a better weight distribution and handling with the front axle moved forward.
So what do you think? This is the '84 Grand Prix with a 112" wheelbase...
(BTW, you can open the first one, then open a new tab for the second one and toggle between them to see the effect)
