As of late I've got nothing but compliments about my regal. The engine swap probably helps a great deal because it sounds pretty mean. But even then I've had people who haven't even heard it run say that it's badass. Even my brother in law who gave me a lot of crap in jest about buying both my regals gave me compliments once I had done the engine swap.
I honestly don't think you'll be getting much crap from people under a certain age as long as your car is in decent shape and running. These cars are finally old enough that younger people don't remember when they were a dime a dozen and held the stereotype of being associated with trashy people, because they were cheap, and older folks might make them feel a bit nostalgic. Also due to their age you pretty much have to be a gear head to keep them on the road so they don't really make a good beater car anymore.
Gbodies are like VW bus's and hippies or camaro's and mullets. I think they'll probably always have that stigma but people will generally appreciate them.
So what do you all think the new car that carries a stigma with it? I think the early 2000s Ford Taurus with the rear end sagging is pretty typical. That or Prius's or smart cars being driven by hipsters.
