Some cars that look like other cars...

When I was a kid, my Dad used to comment how some cars on the road looked like other cars from other manufacturers.
I'm sure you have noticed that too.
Some say that the Duster, Demon and Dart Sport look like a 68-72 Nova.
The recessed rear window in a 68-70 Charger looks like the rear window in a 66-67 Chevelle or GTO.
The angled taillights in a 69 Satellite/Road Runner look like a 67-69 Dart.
The 71-74 B bodies took after the 68-72 GM Chevelle, GTO, Skylark and Cutlass.
I wonder if the roof and rear window of the 66-67 Charger were designed after seeing the AMC Marlin.
What similarities have you seen between different cars?
