I would not describe my auto V6 Mustang as a "musclecar" (although it has the same HP as my '88 Mustang GT), but gaps in the freeway for me are as simple as a push on the O/D button (5th into 4th) and a light squeeze on the gas.
No dramatics, no tiny engine buzzing at the redline, no F-16 like G forces...
You can tell the little Honda Civic I am talking about is occasionally unhappy with it's treatment because it refuses to upshift back into O/D by itself. He has to tweek the auto shifter.
I sure am glad there's a big airbag in front of me and one on the side...
